Liquid Silicone Rubber/LSR
Liquid Silicone Rubber(LSR)
Liquid Silicone Rubber(LSRs) are low viscosity and high purity elastomers with two-part catalyzed silicone specifically designed for liquid injection molding. Each elastomer is supplied in a two-part kit (Part A and Part B), equal portions (by weight) of which must be thoroughly blended together prior to use. When blended and cured as indicated, the resulting elastomer consists of cross-linked dimethyl and methyl-vinyl siloxane copolymers and reinforcing silica.
Cure system - Platinum-Cured
Liquid Silicone Rubber(LSRs) are platinum-catalyzed, addition-cure products. This means no by-products and no release of substances that could impair odor or taste. And curing times are fast, too.
Other Common Variations
•Liquid Silicone Rubber are noted for their high transparency and excellent mechanical and electrical properties.
•Liquid Silicone Rubber applications are numerous, including the automotive, aerospace, appliance, medical, electrical and consumer industries.
•Liquid Silicone Rubber can be formulated with only "white list " ingredients as specified in 21.CFR 177.2600 for use in applications where the elastomer will be in contact with food or beverages.
•Liquid Silicone Rubber parts can be used in medical system which especially require compliance to USP CLASS VI.
