What is liquid silicone rubber (LSR)?
Liquid silicone rubber (LSR) is a two-part, platinum-catalyzed silicone elastomer designed for liquid injection molding. It offers excellent flexibility, durability and resistance to a wide range of temperatures and providing biocompatibility and chemical stability. LSR is widely used for high-volume production of precision parts in medical devices, in which consistent quality and safety are critical.
