Liquid Silicone Rubber

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 in durometers of 10 to 50 Shore A. The LSR System is supplied in two component kits consisting of equal amounts of Part A and Part B. Also available are 10:1 systems, designed to be mixed at 10 parts base (Part A) to 1 part crosslinker (Part B). Advantages over peroxide catalyzed systems include:

• Improved clarity
• Fast cure at elevated temperature
• No peroxide residue
• No volatile by-products
• Ideal for high production, automated LSR equipment
