KURALPHA™ AX by Kuraray is polymethyl methacrylate (PMMA). It offers excellent UV resistance, surface hardness and weatherability. It allows for a closer distance between LED emitter and lens/cover and enables the application of high-power/high-brightness LEDs.
- It enables innovative and aesthetically pleasing designs.
- It provides high heat resistance, good durability, high transparency and flow.
- It is particularly important for modern vehicle lighting, which often requires complex shapes and clear lines.
- It improves the productivity of molded products such as HUD lenses as it reduces defects in thick-wall molding.
- It is recommended for exterior lights like headlights, brake lights and light guides.
