COC: TOPAS® Adopted for LED Valve Cover
 
For this part, PC has been adopted, however, heat resistance has been insufficient in certain uses and improvements in heat resistance have been required.
This time, TOPAS® high heat resistant grade 6015S-04 having heat resistance greater than conventional material is newly adopted for high diffusion lenses so that problems such as heat resistance are resolved.
Newly adopted COC: TOPAS® is an amorphous olefin copolymer having features such as high transparency (visible light transmittance: 90% or more) and high heat resistance (HDT: 150℃).
