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 twopart 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 – Sulfur – 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.
