Liquid Silicone Rubber (LSR) is a high-performance material with excellent mechanical properties, heat resistance, and biocompatibility. It is produced by mixing a two-part liquid compound, typically consisting of a platinum-catalyzed silicone gum and a reactive silicone fluid. LSR is widely used in various industries, including automotive, medical, and consumer electronics, for applications such as seals, gaskets, valves, and keypads.

China is one of the major producers of LSR, with a significant production capacity and competitive prices. The country has a large number of silicone raw material suppliers, providing a stable supply chain for LSR production. Additionally, Chinese manufacturers have been actively investing in research and development to improve the quality and performance of LSR products, making them more competitive in the global market.
