        Silicone rubber is a molecular chain both inorganic and properties of the polymer elastic material, it has the molecular backbone of alternating silicon and oxygen atoms, silicon oxygen bond than the general carbon-carbon bond can be much larger, which makes the silicon rubber with high thermal stability. Heat vulcanized silicone rubber silicone rubber products is one of the most important, methyl vinyl silicone rubber is one of the main varieties, commonly known as high temperature glue.

        Methyl vinyl silicone rubber is a colorless, odorless, non-toxic, no mechanical impurities colloidal material, rubber press need to join the appropriate reinforcement agent, structure controlling agent, curing agent and other additives with the mixing, and then heated molding or extrusion molding made into various products. The products have excellent electrical insulation, arc resistance, corona, electric spark ability strong, waterproof, moisture-proof, shock resistance, good shock resistance, physiological inert, permeability and other properties. Is mainly used for aviation, instrumentation, electronics, metallurgy, machinery, marine, automotive, medical and public health departments, to do all kinds of shape of the sealing ring, gasket, tube, cable, can also make the body organs, vascular, breathable film and rubber molds, precision casting mold release agent.

Silicone rubber has excellent heat aging and aging, ultraviolet and ozone effect is very stable. Silicon oxygen chain in a spiral configuration, molecular chain flexibility big, molecular chain interaction of weak, these features make it soft and elastic rubber, but poor physical properties.

Now compare the successful preparation of high strength silicone rubber method:1 the treated silica, for example with six methyl two silazane treated fumed silica, silica, high tear resistance, tear strength of up to 40~50kn/m.2 in the vinyl silicone rubber with high vinyl content, and of low relative molecular weight of polysiloxane, a silica as reinforcing agent, silicone structure controlling agent, the tear strength is improved.
