Applied Silicone Implant Grade Liquid Silicone Rubber (LSR) Systems are two part, 100% solids, pure dimethyl silicone elastomers, engineered for use in liquid injection molding (LIM) processes where high strength molded parts are desired for medical devices. Liquid Silicone Rubber (LSR) is a pumpable, colorless, translucent paste. When A and B components are mixed together in equal portions, the liquid will cure to a tough, rubbery elastomer via addition-cure chemistry. Custom formulation of radiopaque or color masterbatch is available upon request. This product is available 40 durometer, Shore A hardness. The LSR System is supplied in two component kits consisting of equal amounts of Part A and Part B. Advantages over peroxide catalyzed systems include:
