Silicone LED LensSilicone led lens is also know as silicone light lens, made of clear molding silicone material- dow corning ms 1002, with good optics and flame retardancy. The latest generation of LED lights can reach very high temperature, which will put stress on many traditional polymers, like PMMI, PMMA and PC. However, silicone is highly flexible and can be easily adapted to the end application.
