Silicone rubber is a transparent or milky granular solid. With an open porous structure, strong adsorption, adsorption of a variety of substances. Such as: moisture absorption, moisture content of about 40%. Such as the addition of cobalt chloride, blue when dry, red after water absorption. Repeated use of renewable. The following are the types and characteristics of silicone rubber.
High temperature vulcanized silicone rubber is colorless and transparent, plastic, a molecular weight of 350 thousand to 700 thousand, can be dissolved in solvent such as benzene, product oxidation resistance, ozone resistance, high electrical insulation resistance, arc resistance, corona resistance, and air permeability and on human physiological inertness.
Room temperature vulcanized silicone rubber is characterized in that it can be made of different viscosity of the rubber material, can be coated at room temperature, without high temperature and pressure can be vulcanized, to release the release of alcohol, acetic acid and other low molecular products.
The silicone rubber with polysiloxane vinyl terminated with hydrogen polysiloxane as the base material, with platinum compounds as catalyst in slightly higher than room temperature vulcanization: Sheng SiCHCH2 + HSi Sheng, Sheng SiCH2CH2Si Sheng.
The above three points of knowledge is about the types and characteristics of silicone rubber, I hope to help you, we warmly welcome all customers to come to our company to negotiate business, we are willing to work with you for common development and create a better future!
Silicone rubber has excellent heat resistance, cold resistance, dielectric properties and ozone resistance and ageing resistance properties, outstanding performance of silicone rubber is the use of wide temperature, at -60 DEG C (or lower temperature) to +250 DEG C (or higher temperature) under long-term use. But the tensile strength and tear strength poor mechanical properties of silicone rubber at room temperature, the physical and mechanical properties than most synthetic rubber, and in addition to silicone, silicone rubber, silicone rubber general oil resistance, solvent resistance is poor, so the silicon rubber should not be used for the general conditions of the occasion, but very suitable for many special occasions.
The silicone rubber products have excellent performances and good technical and economic effect, has been in the aviation, aerospace, atomic energy, electrical, electronic, widely used instrument, automobile, machinery, metallurgy, chemical industry, medical and health, daily life in all areas.
