Application
Plastic resins for Lighting & Optical
Transparent resins for lenses, diffusers, light guides and covers, chosen by light transmission, impact strength and heat resistance.
Typical parts
- LED diffusers and covers
- Light guide plates
- Automotive lamp lenses
- Street-light covers
- Display and signage panels
What the material has to do
- 01Light transmission
High clarity and low haze, with stable color over time.
- 02Impact strength
Outdoor and automotive covers must resist hail, stones and vandalism.
- 03Heat resistance
Covers close to LEDs and lamps must not deform or yellow.
- 04UV and weathering
Outdoor parts need UV-stabilized grades.

Lighting & Optical: common questions
PC or PMMA for a light cover?
PMMA for the best clarity and scratch resistance indoors; PC when the cover must take impact or heat.
