Makrolon® DX Line Solid polycarbonate sheet for LED lighting

Product Data Sheet, January 2014
Makrolon® DX Line
Solid polycarbonate sheet for LED lighting
Your benefits:
• extreme high light transmission and high diffusivity at the same time
• extreme impact strength
• resistance to wide range of temperature
Solid Makrolon® DX sheets are polished polycarbonate diffuser
sheets. Makrolon® DX is developed for applications based on LED
light sources, which do not emit UV light. It offers a combination of
high light transmission and light diffusion as well as an extreme impact
strength which exceeds the physical properties of other thermoplastics.
Makrolon® sheets resist tempe-ratures of -100 to +120 °C.
Makrolon® DX warm is a diffuser sheet with a warm and pleasant color
appearance, especially when backlit with cold white LEDs. Makrolon®
DX warm enhances color rendering of light coming from red, green,
blue LEDs and/or from the combination thereof.
Makrolon® DX cool is a diffuser sheet with a cool and fresh color
appearance, even when the LEDs are in off mode.
Makrolon® DX-NR (warm/ cool) is a diffuser sheet with one side matt
finish to prevent glare and reflections. The matt side contains also UV
protection for improved weatherability.
Makrolon® DX-UV (warm/cool) is a diffuser sheet with one side UV
protection for improved weatherability.
Makrolon® DX-NR and Makrolon® DX-UV are the perfect choice for
a long service life because of their good weathering performance, backed up by a 10-year warranty. Attention: the sheet must be mounted
with the UV protection layer facing the sun.
Applications:
Typical applications for Makrolon® DX diffuser sheets include all kinds
of LED lighting fixtures and luminaires. The sheets offer protection
against involuntary breakage and willful destruction therefore can also
be applied in LED-based signage applications and street furniture
where efficient lighting technologies are in use. Makrolon® DX sheets
can be thermoformed, cold-curved and fabricated with ease.
