HTV is a polymer polysiloxane, with a molecular weight of 400,000 ~ 800,000, which is mainly used to manufacture various silicone rubber products. HTV is a high elastic vulcanizate after adding vulcanizing agent and other coordination agent in silica gel, which is heated to produce crosslinking reaction of rubber molecules. It has good processing performance, molded rubber with "double 2,5" curing agent curing, suitable for the production of ordinary silicone rubber products and miscellaneous, ordinary silicone rubber keys, especially suitable for color products; The extruded rubber is vulcanized with "double 2,4" vulcanizing agent, which is suitable for the production of low grade silicone rubber extruded products.

With HTV can produce higher product hardness and elasticity good silicone products, general, hardness, tensile strength, tear strength and other performance is good, is mainly used in aerospace, instrumentation, electronic appliances, navigation, metallurgy, machinery, automobile, medical and health departments and so on, can make various shapes of sealing ring, gasket, pipe, cable, also can do human organs, blood vessels, breathable membrane, and rubber mould, Release agent for precision casting, etc.
