HTV is the most important category of silicone products, and methyl vinyl silicone rubber (VMQ) is the most important variety in HTV. Methyl vinyl silicone rubber (raw rubber) is a colorless, odorless, non-toxic, non-mechanical impurity colloidal substance. The raw rubber is mixed with appropriate reinforcing agents, structure control agents, vulcanizing agents and other additives as needed. Then it is heated to 140~180℃ for high temperature compression molding or extrusion molding, and then it is made into various products through two-stage vulcanization.

In addition to the characteristics of vinyl silicone rubber series, this product also has excellent low temperature resistance, radiation resistance, combustion resistance and self-extinguishing properties. It is one of the important materials in the aerospace industry and is a cutting-edge technology. It can be used in various molding and extrusion products, and used for cold-resistant, combustion-resistant, heat-aging and radiation-resistant parts of seals, gaskets, pipes and bars. It can also be used to manufacture various special-purpose products, such as: making damping materials and pressure-sensitive adhesives.
