Features & Benefits

Superior Optical Clarity & UV Protection

This LEXAN OQ4005 resin offers >87% light transmission with minimal haze, ensuring crystal-clear vision. Its built-in UV stabilizer blocks harmful rays up to 400 nm, significantly enhancing product longevity and user protection in outdoor applications.

Exceptional Durability and Impact Resistance

With a “No Break” rating in unnotched Izod tests, this material provides outstanding toughness and safety. This superior impact resistance of LEXAN Resin OQ4005 reduces breakage risks, ensuring reliable performance in demanding eyewear and visor components.

High Heat Resistance for Stable Performance

A Vicat softening point of 145°C ensures the resin maintains its shape and integrity under high temperatures. This thermal stability allows for use in environments where other plastics might warp, supporting consistent quality during both processing and end-use.
