How much do you know about the properties and physical properties of silicone rubber?Today xiaobian according to this problem for you to do a detailed introduction.
Silicone rubber characteristics have the following advantages:
(1) Excellent heat and cold resistance, can be used in -60 ~ 250℃ for a long time
(2) good ozone resistance and weather resistance
(3) Good electrical performance
Silicone rubber is a non-toxic material, widely used in automobiles, aerospace, electronics, machinery, daily necessities, medical and so on
Silicone rubber wire is made of high quality silicone rubber and high purity tinned copper stranded wire.With high and low temperature resistance, insulation and other advantages.Widely used in household appliances, lighting, industrial machinery, electric heating products and other high-temperature wiring.Extra-soft silicone rubber wire is generally used for internal connecting wires of electronic and electrical equipment, such as motors, etc., which is different from ordinary wires.
Characteristics of silicone rubber.Silicone rubber is divided into coarse silicone rubber and fine silicone rubber
Silicone rubber can absorb water, acetylene and carbon dioxide.As the temperature decreases, the first adsorption is water (normal temperature, about 25℃), followed by acetylene and carbon dioxide (the lower the temperature, the stronger the adsorption capacity).
Because this rubber contains a small amount of vinyl side chain, it is easier to vulcanize than methyl silicone rubber, so that more kinds of peroxides can be used for vulcanization, and can greatly reduce the amount of peroxide.Using a small amount of vinyl silicone rubber compared with dimethyl silicone rubber, can make the compression resistance of permanent deformation significantly improved, low compression deformation reflects it as a seal at high temperature has better support, which is one of the requirements of o-ring and gasket must have.Methyl vinyl silicone rubber process performance is good, easy to operate, can be made into thick products and pressing, rolling semi-finished products smooth surface, is a commonly used silicone rubber.
