Supplied byKuraray- Last Updated on Aug 28, 2025

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