High temperature vulcanized silicone rubber(HTV) is the most important type of silicone products, and methyl vinyl silicone rubber(VMQ) is the main type of HTV.
HTV is a kind of rubber compound which is made by adding silicone rubber raw material to double roll rubber mixer or closed kneader and gradually adding silica, silicone oil and other additives.
The products have good physical and mechanical properties, excellent thermal stability, high and low temperature resistance, and can work for a long time at - 50 ℃ ~ +250 ℃.
It can be widely used in aviation, cable, electronics, electrical appliances, chemical industry, instrument, cement, automobile, food processing, medical equipment and other industries, for molding and extrusion processing molding. Its products have excellent chemical stability, weather aging resistance, physiological inertia, air permeability and other properties.
It is suitable for the production of ordinary silicone rubber products and silicone parts with good processing performance, such as various of sealing rings, gaskets, silicone tubes, ordinary silicone rubber keys, rubber molds, etc.
