Chemical Resistance
Griphen™ Frost shows a good resistance to a number of chemicals. The overall chemical resistance is however
dependent upon the following parameters:
· temperature (resistance decreases with higher temperatures)
· stress level (best resistance is with flat sheet, clamped in a frame)
· chemical concentration (mostly in water, from some ppm to pure)
· exposure time (from fumes over drips to continuous contact)
Following information is meant as a guideline. As to the above influences, it is recommended to perform own testing
according to the final application.
Do not hesitate to contact us in case of questions regarding the chemical compatibility of Griphen™ Frost.
In case you want Arla Plast to perform compatibility testing, the product and its MSDS, together with indications on
above parameters are required.
In general, Griphen™ Frost shows a good chemical resistance for various chemicals such as dilute solution of acids,
salts and aliphatic hydrocarbons, but it is significantly affected by aromatic hydrocarbons and ketones. All tests are
performed on flat sheet, immersed in the reagent at room temperature

1 GENERAL
General Guidelines
Griphen™ Frost sheet can be worked with most tools used for machining wood or metal. Tool speeds should
be such that the sheet does not melt from frictional heat. In general, the highest speed at which overheating of the
tool or plastic does not occur will give the best results.
It is important to keep cutting tools sharp at all times. Hard, wear-resistant tools with greater cutting clearances
than those used for cutting metal are suggested. High-speed or carbon-tipped tools are efficient for long runs and
provide accuracy and uniformity of finish.
Since plastics are poor heat conductors, the heat generated by machining operations must be absorbed by the tool
or carried away by coolant. A jet of air directed on the cutting edge aids in cooling the tool and in removing chips.
Plain water or soapy water is sometimes used for cooling unless the trim scrap is to be reused.
Griphen™ Frost surface might whiten locally when stressed in cold state, like cold bending, die cutting, etc.
Also surface friction might cause similar discolouration. This effect can be reduced by local heating (hot air or
flame), but will be very difficult to delete fully.
2 SAWING
Circular saw
The table saw type is the most frequently used for sawing flat sheet. When sawing thin gauge sheet, decrease saw
speed, feed rate and pitch. Keep the gap between blade and table as small as possible.
Ensure that the table is free of particles that may damage the masking and scratch the Griphen™ Frost sheet.

suitability for a specific application, and he is also liable for observing any proprietary or third party rights. It is always advisable to do preliminary testing.

Band saw
Band saws are used to cut out formed parts, or irregular shapes. For a series of the same shape, a supporting
calliper can be useful in preventing chipping. Thicker gauges are best sawn with a bigger tooth size.
To achieve a smooth edge, circular saws and routers are preferable to a band saw.

Trouble shooting
Chipping :Increase blade tooth size and saw speed, decrease feed rate.
Gumming: decrease blade tooth size and saw speed, increase feed rate.
Cracks or notches: as for chipping, check clamping.
In all cases, inspect blade sharpness, check blade fence alignment and if needed use air to cool blade. Change of
sound or vibration during sawing, is an indication that sharpness and alignment might have changed.
3 ROUTING
Routing is especially recommended for trimming workpieces. Always use routers of at least 750 Watts, and a
speed of 18 000 to 25 000 rpm is preferred. Bits should be straight fluted preferably two-fluted, carbide-tipped, or
high-speed steel, with a diameter of 4 to 12 mm. Always feed counter rotation-wise up to 1.5 m/min, and cool with
compressed air only.

4 SHEARING, BLANKING, PUNCHING & DIE CUTTING
Griphen™ Frost surface might whiten locally when stressed in cold state, like cold bending, die cutting, etc.
Also surface friction might cause similar discoloration.
Shearing and Punching
Shearing will produce linear straight-edged cuts, while punching and blanking can produce a variety of shapes.
These fabrication methods can be used on Griphen™ Frost sheet in 2 mm. For thicker sheet, routing is
preferable to above mentioned techniques. It is important to adjust the blade clearance in relationship to the bed
knife. A clearance of approx. 0.025 mm is desirable to avoid a rough edge cut. Cracking and chipping can be reduced
by heating the sheet to max 45°C; however, some allowance for hole shrinking due to cooling may be necessary.
This information is given in good faith and to the best of our knowledge, but without warranty. Each user of our materials should determine himself the
suitability for a specific application, and he is also liable for observing any proprietary or third party rights. It is always advisable to do preliminary testing.

page 7
Die Cutting
This is a technique frequently applied to paper. Griphen™ Frost can be die cut up to 2 mm, with steel rule dies
(A ribbon of steel bent to any desired contour and mounted in or around a block of wood). Blades of 0.8-1 mm
thickness work well. The steel rule must be sharpened or replaced fairly often.
Symmetric double bevelled blades (15 & 30°) are recommended. For thicknesses above 1.5 mm asymmetric
blades should be used. To obtain straight edges, one side bevelled blades under 30° must be used.
Keep the back-up pad (made out of nylon or HDPE high density polyethylene) in good shape and ensure a perfect
alignment of the die and the pad to obtain appropriate cuts.
Adequate power in the die press is needed to achieve the desired cut..
The die press tonnage can be calculated using following formula:
F(Tons) = S x t x P/ 10 000
S = Shear strength = 33 (Mpa)
t = thickness in mm
P = Perimeter of cut in mm

Sandt AG
5 DRILLING
Drills designed for plastics are recommended, but standard twist drills for metal will do the job as long as they have
not been used on metals before, though they require slower speeds and feed rates to produce a clean hole.
For deep holes, in the edges of thicker gauge sheet for example, cool with compressed air and frequently back out the
drill to free chips and prevent melting of them. Never use cutting oils. Like other transparent plastics.
Griphen™ Frost is a notch-sensitive material and cutting threads develop stress points that can create stress crazing
or cracking. Always keep a distance from the edge, minimum 1.5 times the diameter of the hole. Be sure drilled holes
are smooth with no evidence of cracks or roughness, which can cause breakage when fastening.
Do not use countersunk screws with Griphen™ Frost sheet. (see mechanical fastening)

6 TAPPING
Be aware that tapping will create notches in the part, which might decrease local impact resistance and stress
resistance.
Conventional 4-flute taps can be used for cutting internal threads in plastic sheet when a close fit is required. Such
taps, however, have a tendency to generate considerable heat during the tapping operation. A high-speed, 2-flute
tap will offer longer life and greater tapping speed than a conventional tap, and provide clearance for chip discharge.
In order to obtain uniform thread, flutes should be ground so that both edges cut simultaneously.
Cutting edges should be 85° from the centre line, giving a rake of minus 5° on the front face of the lands so that the
tap will not bind in the hole when it is backed out. It is desirable to have some relief on the sides of threads.
7 MILLING
Standard high-speed milling cutters for metal achieve best results, provided they are sharp (not been used on metal
before) when applied on.
Typical parameters are 500 rpm and feed 0.25 mm/rev.
8 LASER CUTTING
Lasers can be used to cut Griphen™ Frost, giving clear edges up to 5 mm thickness. The result of the cut depends on
the installation and its parameters. Preliminary cutting-tests are recommended. . Laser power and travel speed
must be optimised to minimise ‘whitening’ of the Griphen™ Frost sheet while cutting.
Fumes coming off during
cutting might smell unpleasant and therefore it is recommended to use appropriate exhaust systems.
Do not to induce stress into freshly laser cut sheet (e.g. cold brake forming), as breakage might occur.
Therefore it is recommended to anneal the sheet (max 50 °C) or stock it for some time (min 1 week) prior to that
specific forming technique.

1 COLD FORMING
Griphen™ Frost surface might whiten locally when stressed in cold state, like cold bending, die cutting, etc.
Also surface friction might cause similar discoloration. This effect can be reduced by local heating (hot air or flame),
but will be very difficult to delete fully.
Cold curving
Griphen™ Frost can be cold curved with a minimum radius of 175 times the gauge thickness for outdoor
applications, and 125 times the thickness for indoor applications (Note that when exposed to UV radiation Griphen™
Frost will age similar to PETG sheet). When smaller radii are needed thermoforming is the solution.
Cold bending & brake forming
Due to surface whitening on the bend zone, this technique is not recommended for esthetical reasons.
The alternative is hot line bending.
2 THERMOFORMING
Griphen™ Frost sheet retains its matt surface even when formed with higher draw ratios.
Surface friction has to be reduced to a minimum to avoid local surface whitening. In some cases this whitening can
be reduced by locally heating the area with hot air or by means of a flame.
Griphen™ Frost sheet does not need to be pre-dried and can be thermoformed at low temperature (110155°C). Sheet temperatures over 160°C may cause blistering and damage the sheet.
The adhesive masking on the Griphen™ Frost sheet has to be removed prior to any thermoforming technique.
Take care while heating the sheet. Heating too fast will result in heat accumulating at the sheet surface and
degrade it. Because of its low specific heat, Griphen™ Frost sheet requires only a little energy to be formed.
The most appropriate heaters are infra red heaters. Contact heating and high-frequency heating are not suitable.
Halogen heaters only are suitable for coloured sheet.
This information is given in good faith and to the best of our knowledge, but without warranty. Each user of our materials should determine himself the
suitability for a specific application, and he is also liable for observing any proprietary or third party rights. It is always advisable to do preliminary testing.

page 10
Hot line bending
The Hot Line Bending equipment is a simple IR- or electrical resistance heater, bending-calliper coated with fabric
and a clamping device.
To keep the finished part protected, the masking can be removed locally on the bend zone alone. Perform a
preliminary test to find out the correct heating time.
The heating time depends on the power of the IR heaters. With one side heating, it takes about 2 min to make a 3
mm sheet weak enough to bend. Thicker sheet need to be heated from both sides. If not available, turn periodically
during the heating cycle. Always bend the sheet with the last heated side forming the outside radius.
When Griphen™ Frost softens, remove from heating source, bend, place into calliper and clamp.
Cool slowly to prevent distortion. Keep the part close to the heating device to make it cool down evenly. Once the
part is at about 75 °C, it can be placed in a fixing device and cool down in the air.

Drape forming
Uni-axial bent parts can be achieved by drape forming. The mould can be made out of wood or aluminium
covered with felt. Slight pressure (with soft gloves or cloth, e.g. linen) is sufficient to drape the Griphen™
Frost sheet over a positive mould.
Remove standard masking before putting into an IR oven to be heated. Preferably the sheet should be
clamped in a frame, as placing it on a bed might mark the sheet. The sheet temperature should be about
130°C to achieve easy forming. Place sheet on the mould immediately after heating; therefore minimise
distance between mould and oven. Cool in surrounding air, but take care for drafts which could cause
distortion of, and stress in the finished parts.
Note that as the sheet is not framed during the process it will shrink during the heating process (for thin
sheet up to 6% in extrusion direction).
Vacuum forming
Griphen™ Frost sheet retains its matt surface even when formed with higher draw ratios.
Surface friction has to be reduced to a minimum to avoid local surface whitening. In some cases this
whitening can be reduced by locally heating the area with hot air or by means of a flame.
Because of its perfect flow properties, Griphen™ Frost sheet, allows you to make the most complex
finished parts. Draw ratios of 4:1 can be achieved. Standard available vacuum forming machines, preferably
with a sandwich heating system, can be used to forem. Griphen™ Frost requires a minimum vacuum of
500 mm Hg (0,66 atm or 0,066 MPa), but higher vacuum is preferred.
Moulds
Depending on series to be produced and the required finish of the parts, one can use different mould
materials. Be aware that the mould material affects both cooling time and finish of the formed parts.
This information is given in good faith and to the best of our knowledge, but without warranty. Each user of our materials should determine himself the
suitability for a specific application, and he is also liable for observing any proprietary or third party rights. It is always advisable to do preliminary testing.

page 11
Design moulds with such roundings that the Griphen™ Frost can slip over; however, friction can cause local whitening.
For a good evacuation of air, it is important to make an optimum number holes in the right places. Inadequately placed
holes might cause optical defects on the formed parts. This may occur especially on parts with large flat surfaces.
A mould temperature of 50-55°C gives best results. To achieve a perfect optical finish, it is recommended to use
temperature-controlled moulds.
Negative and positive mouldings
Negative moulds result in finished parts with a thin bottom and thick walls, whilst positive moulds result in parts
with a thick bottom and thin walls. Depending on the application, either a positive or a negative mould should be built.
For better external finish use negative moulds which show more detail.
Heating
Remove standard protection masking prior to thermoforming, and blow off the sheet and mould with ionised
pressurised air.
When clamped on 2 sides only (e.g. in automatic feeders) be informed that the free side might shrink (see drape
forming). Therefore 4 side clamping is preferred. If a heating profile is available, it is recommended to adjust it as
such that when pre-blown, the sheet forms the same shape as the mould. That way the best thickness spread is
obtained.
Griphen™ Frost sheet requires only 155°C to form even the most complex structures. One side heating is not
recommended for sheets of 3 mm and above. To prevent surface degradation, avoid fast heating. The sheet can only
absorb part of the IR radiation and accumulation of heat will damage the sheet and embrittle the formed part.
Cooling the formed part
Cool with compressed air; possibly with water mist (avoid droplets as they might cause marking). Let the part stiffen
sufficiently and take it from the mould. Shrinkage of Griphen™ Frost is about 0.4%.
Using positive
moulds, shrinkage might cause removal problems. Take care to remove before the part shrinks on the mould. Do not
cool too fast, because the generated stresses may result in cracking. If necessary, post-forming relaxation can be done
at 65-75°C.
Take care when stacking formed parts, as surface friction can cause local whitening.

page 12
Free Forming
These techniques are utilized in forming dome shapes. Free blown billow forming uses air pressure while free drawing
uses a vacuum.
The sheet is heated until a sag is formed. An optical switch and/or a micro-switch are coupled with the pressure
(vacuum).The initial pressure (vacuum) is high (2,8 MPa or more) and is lowered towards the end of the forming cycle.
The pressure (vacuum) is held until the sheet temperature reaches 75°C and the forming is able to be removed. Here
will be no mark-off as no moulds are used, but dirt or oil in compressed air may cause marks on the sheet.
Plug-assist vacuum forming
Corner or periphery thinning of box-shaped articles can be prevented by use of a plug-assist to mechanically
stretch and pull additional plastic material into the female cavity. The plug should be 10 to 20 % smaller than the
mould and should be heated to ca 110-130°C. Once the plug has forced the hot sheet into the mould cavity, air is
drawn from the mould to form the part.
Other methods
Other thermofoming methods are combinations of above mentioned ones.
Plug-assist vacuum forming and plug-assist pressure allow deep drawing and permit shorter cooling cycles and
good wall thickness control. Both processes require close temperature control and are more complex than straight
vacuum forming. High pressure forming (HPF) and Twin sheet forming (TSF) are two advanced methods which for
small to average series can compete with injection moulding and blow moulding.
High Pressure Forming
Using a negative mould, the atmospheric air pressure that spreads the softened sheet over the mould, is increased by
pressurised air up to 1 N/mm2 (10 Kgf/cm2).
Twin Sheet Forming
Two heated sheets are brought between two negative moulds. Air pressure in between those sheet is applied while
the circumference of the sheet is clamped. An alternative technique forms the upper and lower part separately, and
both parts are brought together, the circumference is reheated to obtain fusion of both parts. This technique creates
hollow shapes, to obtain light parts with high structural stiffness.

1 SOLVENT BONDING
Use extreme caution when working with solvents: they may be toxic or contain carcinogens. Adequate
ventilation is essential. Obtain Safety Data Sheets from the solvent manufacturer.
This technique has been used for years to make displays from acrylic sheet, but can also be used to construct
three-dimensional shapes with Griphen™ Frost sheet. To bond small pieces, one can use a hypodermic needle and
making sure that the solvent flows throughout the area to be cemented.
Edge dipping is another method used to assemble two flat parts under a 90° angle. The edge of the sheet which is
to be bonded, is dipped in the solvent until it becomes soft. Then it is put on the flat sheet under slight pressure.
The jointed articles can be safely placed on a table to dry after the solvent has been applied. Special care should
be taken that no air bubbles are left after curing. Both methods depend on smooth edge preparation, pressure and
curing.

When using solvents it is advisable that the work area be climate controlled with low humidity to minimise joint
‘whitening’. If this is not possible, the addition of 10 % glacial acetic acid (boiling point 116.5 °C) to the solvent or
use of a slower curing cement-type bond is suggested. Solvents with a low boiling point, may cause whitening or
insufficient softening of the treated surface which results in improper joints.
To prevent early evaporation, use mixtures of the above mentioned solvents or dissolve Griphen™ Frost chips
in one of them to increase boiling point.

Mixture suggestions :
- 42% MEK, 42% Trichloroethylene and 16% Methylene dichloride
- 85% Methylene dichloride, 12% Trichloroethylene and 3% MEK
When using a solvent in which 8% of Griphen™ Frost chips have been dissolved, the curing time is longer, allowing you
to adjust the position of the two parts to be bonded, and preventing them from whitening.
To obtain above mentioned solvents contact local chemist or drugstore, or check for specialty chemicals suppliers like
www.brenntag.com
2 ADHESIVE BONDING
When working with adhesives, the usual safety and health precautions should be taken and eventual special
instructions from the adhesive manufacturer should be observed.
A lot of commercial adhesives have proven their effectiveness for bonding GRIPHEN™FROST. Types, which can be used,
are Akrifix™118, Extrufix™, Ruderer™118. Adhesives on polyurethane or acrylic basis give good results. Take into account
that stresses in the sheet or parts in combination with solvents or adhesives may cause cracking. For optimum gluing
results remove the surface locally. Cut and finish the surfaces to be bonded carefully.
A good alternative is a 2 component polyurethane adhesive, which exists in a clear transparent grade.

3 RECOMMENDED BONDING DESIGNS
Joint design, often overlooked, should be such that the bonding area carries the load equally, with the major stresses
in tension or shear thereby minimising cleavage and peel stresses. The lap joint is the most frequently encountered
joint type when working with relatively thin gauge materials.

4 TAPE BONDING
Due to its specific matte surface, tape bonding might not give the right results.
Double sided self adhesive tapes, transparent and mostly on an acrylic basis, can be used to make quick
fastenings. These tapes are elastic and stick to different materials. They can be quite useful in bonding thin sheet
materials to other plastics, glass or metals.
Use following procedure to make proper bondings:
· Bend along the part for more than tape width.
· Clean this zone with a 50% Isopropyl alcohol - water solution.
· Pressing with wooden roller evacuates trapped air and improves strength.
Manufacturers of bonding tapes:
3M Company, MACtac Europe S.A., Scapa Tapes
5 MECHANICAL FASTENING
Due to its high impact resistance, all types of mechanical fastening can be applied, depending on thickness of the
Griphen™ sheet up to 1.5 mm, it can be nailed, stapled or riveted. These kinds of fastening are not recommended for
industrial applications.
The best way to fasten Griphen™ is to use screws with a cylindrical head. Never use screws with chamfered heads. They
cause stress cracking. Drill holes 0.5 mm larger than the screw. Screws of plastic can always be used. When using metal
screws or bolts, use plastic washers (nylon). Metal thumbscrews can be used without washers.
Use galvanised types only.
Never use glue to tighten bolts.
No more than 2 extra twists after turning firm by hand.
Mechanical fastening will produce a stronger part than solvent bonded parts and allows for easier disassembly and
cleaning.
6 WELDING
While mechanical fastening and solvent bonding are the most often recommended methods of joining Griphen™ Frost,
another alternative is welding.
Ultrasonic welding and spin welding have both proven to be appropriate. High frequency welding is not suited. Contact
manufacturers of ultrasonic welding equipment for recommendations on section and joint design.
Manufacturers of ultrasonic welding equipment:
Branson Ultrasonics Corp, Pfaff AG
Also possible is hot air welding, using a welding rod made of PETG or if not available locally also a strip cut from a 3 or
4 mm Griphen™ Frost sheet will work well.

Finishing
1 Sanding
2 Polishing
3 Decorating
1 SANDING
The sheet edges can be sanded using both wet and dry systems. Dry sanding can result in gumming as frictional heat
build-up is created. Wet sanding gives a smooth finish. In both cases, further finishing in order to
restore the gloss will be necessary.
Example : start with 80-grit paper and end with 400 or 600-grit.
2 POLISHING
Polishing is a time consuming activity and should only be applied for smaller series and parts made out of thick
gauge sheet. The edges can be polished by different techniques. Keep in mind the specific colour of Griphen™:
a glass clear edge will rarely be achieved.
Mechanical polishing
After grinding, surfaces of Griphen™ Frost sheet can be polished in order to obtain a better surface finish. Burnish
wheels of cloth or fleece and felt polishing bands, together with a suitable polishing wax, give good results. Keep
surface temperature low, in order to a later appearance of fine cracks. Suppliers of mechanical polishing tools:
Suppliers of mechanical polishing tools:
3M, EFC (US)
Diamond polishing
Griphen™ Frost sheet can be diamond polished resulting in an excellent surface quality that does not need further
treatment. No pre-grinding step is required, as per step up to 0.5 mm can be removed.
Suppliers of Diamond polishing tools:
Shannon B.V., EFC (US)
Flame polishing
Use a standard propane - or butane torch or a hot nitrogen welder. It is very important to control the distance
between the sheet and the heat source. Without proper control, surface whitening or material flow of the Griphen™
Frost might occur.

page 20
nstead of a torch, an electrical hot air device can be used.
As with Acrylics, flame polishing Griphen™ Frost sheet can cause long-term edge cracking. However, with
continued practice and by using proper techniques, excellent results can be achieved.
Solvent polishing
The appearance of saw-cut edges can be improved by first sanding them. For smoother, glossy edges, consider
solvent polishing with MEK or methylene dichloride. To prevent humidity blush after drying, add a small amount of a
slow-drying component such as diacetone alcohol.
Use extreme caution when working with solvents. Adequate ventilation is essential. Follow precautions Safety
Data Sheets from the solvent manufacturer.
3 DECORATING
Flat sheets can be screen printed, tampon printed, hot stamped or decorated with self adhesive films. Vacuum
formed parts can be tampon printed or hot stamped.
Other techniques are (spray) painting, laser marking, sand blasting, …
Hot stamping
Griphen™ Frost sheet or formed parts made out of Griphen™ Frost are easily decorated by hot stamping. Decoration
can be done on single pieces (vertical stamping or roll-on stamping) upto continuous pieces. Special types can be
thermoformed. Typical conditions are:
Die temperature: 190 °C
Pressure: 0.4 N/mm2
Dwell time: 2-3 seconds
Hot stamping foil / tools manufacturers:
Leonhard Kurz GmbH & Co, John T Marshall Ltd
Screen printing
Griphen™ Frost sheet can be printed with conventional printing equipment. In general, printing inks which are
compatible with thermoplastic oriented polyesters (PET) work well. Since the ink does not penetrate GRIPHEN™
FROST as it does with paper or fabric, it is subject to abrasion. This problem can be minimised by applying a clear
top lacquer over the printing.
All standard Griphen™ Frost sheets have an adhesive polyethylene masking. It is very important to ensure
the sheet is clean and free from dust and dirt prior to screening. Use ionized air to remove dust.
Be careful not to exceed 65°C during the cure process.
In case of questions, please consult your ink supplier.

Cleaning
Griphen™ Frost sheet may be cleaned by using a clean soft sponge and washing with lukewarm water
containing a mild soap or a slightly acidic, neutral or slightly alkaline detergent. Then rinse thoroughly with clean
water and dry with chamois leather or a moist sponge. A subsequent anti-static treatment is recommended.
Fresh paint splashes, grease, smeared glazing compounds, etc. can be removed before drying by rubbing lightly
with isopropyl alcohol on a soft cloth followed by a thorough wash and rinse as described above. Rust stains can
be removed with a 10% oxalic acid solution.
Do not use abrasive or highly alkaline cleaners, acetone, benzene, leaded gasoline or carbon tetrachloride on
Griphen™ Frost sheet.
Never scrape with razor-blades or other sharp instruments. Having good electrical insulating properties,Griphen™
Frost sheet is subject to electric static charge and dust attraction. Treatment with an anti-static agent keeps the sheet
free from static charge and dust over prolonged periods.
There are some commercially available products which act simultaneously as cleaning agent and anti-static agent.
Before commencing certain operations on Griphen™ Frost sheet such as painting, screen printing or
thermoforming, it is recommended that dust particles be blown off first, using an ionised air gun. Dusting with a
regular air gun or a cloth only moves the particles rather than removing them.
