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.

Carboxylated Nitrile ( XNBR )

XNBR Carboxylated Nitrile ( XNBR ) Cabboxylated Nitrile is similar to Nitrile rubber, but the polymer backbone has been chemically modified with Carboxylic Acid containing group. This result is XNBR with more excellent abrasion and tear resistance than traditional NBR. For this reason, XNBR based parts are usually applied in dynamic assembly such as seals and rod wipers. Cure system - Sulfur - Cured Standard XNBR compounds are sulfur-cured Performs Well In… ►Aliphatic hydrocarbon ►Vegetable and mineral oils and greases ►Diesel ►Water Dilute acids, alkali and salt solutions Doesn't Perform Well ...

Silicone Rubber ( MQ, VMQ, PVMQ )

VMQ Silicone Rubber ( MQ, VMQ, PVMQ ) Physically, silicones are based on silicon, an element derived from quartz. To create this class of synthetic elastomers, pendant organic groups such as methyl, phenyl and vinyl are attached to silicon atoms. The different addition of side chains can achieve significant variations in properties. Silicones have excellent heat, ozone and corona resistance, very well dielectric stability, and resistance to many oils, chemicals, and solvents. And for all elastomers, silicones possess the best flexible property ...
