HTV is the most important type of silicone products, and methyl vinyl silicone rubber (VMQ) is the most important variety of HTV.

Methyl vinyl silicone rubber (raw rubber) is a colorless, odorless, non-toxic and mechanical impurities free rubber. The raw rubber is mixed with appropriate reinforcing agent, structure control agent, curing agent and other additives as required, and then heated to 140~180 ℃ for high temperature molding or extrusion molding, and then vulcanized to make various products.

This product not only has the characteristics of vinyl silicone rubber series, but also has excellent low temperature resistance, radiation resistance, combustion resistance and self extinguishing performance. It is one of the important materials and cutting-edge technology in aerospace industry. It can be used for various molding and extrusion products, as well as cold, combustion, heat aging and radiation resistant parts of sealing rings, gaskets, pipes and bars. It can also be used to manufacture various products for special purposes, such as damping materials and pressure-sensitive adhesives.
