With the popularity of automobiles, the application of high-transparency lens headlights has gradually spread to medium and low-end models, two-part optically clear silicone rubber material has been widely used in LED packaging. The traditional glass optical lens can no longer meet the market demand due to its fragility, complex processing, easy yellowing, and other defects. The optical-grade liquid silicone raw material with unique characteristics such as light transmittance of 95%, UV resistance, physical stability, etc. solves the problem of yellowing and has become a new favorite for manufacturing lens headlight packaging.

Liquid silicone rubber(LSR) Material is considered a better material than conventional plastics because of the health and economic advantages it brings. Unlike plastic products which contain the harmful substance BPA, LSR products do not contain harmful ingredients, which makes them safer for humans. In addition, its high durability, temperature resistance, and chemical resistance also make silicone products last longer than other materials. Therefore, it is widely used in electric breast pumps, manual breast pumps, silicone nipple shield, and other baby products.
