Product Introduction:
The general molded silicone rubber compound is the basic product for molding rubber, which is easy to open, color and process. Rebound after vulcanization Good performance, low compression permanent deformation, and good physical and mechanical properties.
Silicone rubber has excellent resistance to high and low temperatures, ozone, high temperature service life, and mechanical strength at high temperatures. The heat resistance of silicone in air It has much better properties than organic glue, and its physical properties remain basically unchanged at 150 degrees, making it suitable for semi permanent use.
Product application:
Widely used in the production of various buttons, rubber plates, sealing gaskets, leather bowls, valves, films, shock absorbers, electrical plugs, potentials Insulated sleeve, diaphragm, rubber plug, O-ring, and rubber roller
