Characteristics and Applications of Silicone Rubber

- Sep 26, 2019-

Main properties and applications of silicone rubber: silicone rubber according to its vulcanization temperature, can be divided into high temperature (heating) vulcanization type and room temperature vulcanization type two categories, high temperature rubber is mainly used for manufacturing various silicone rubber products, and room temperature rubber is mainly used as adhesives, potting materials or mold use.

Hot vulcanized silicone rubber (HTV) is the most important type of silicone products, methyl vinyl silicone rubber (VMQ) is the most important variety in HTV, commonly known as high temperature adhesive.Mainly used in aviation, instrumentation, electronic appliances, navigation, metallurgy, machinery, automobile, medical health and other departments, can do various shapes of sealing ring, gasket, pipe, cable, also can do human organs, blood vessels, breathable film and rubber mold, precision casting mold release agent.

Room temperature vulcanized silicone rubber (RTV) generally includes two categories: condensation type and addition molding.It has good heat resistance, hydrophobicity, electrical insulation, and excellent physical and mechanical properties due to the introduction of active end groups, especially in the tensile strength, relative elongation and tear strength has been significantly improved.It is applicable to various vulcanization methods, such as radiation vulcanization, peroxide vulcanization and molding vulcanization, widely used in heat, moisture, electrical insulation, high strength silicone rubber products.The demand for these varieties is relatively small, but in many cases indispensable.
