Phenyl silicone rubber is a new type of silicone rubber material developed internationally to meet the increasing requirements for high and low temperature resistance. By introducing phenyl groups on the side groups of polysiloxanes, methyl phenyl tricyclic (A3) It is formed by ring-opening polymerization and modification together with methyl mixed ring (DMC) and vinyl ring (VMC). Its temperature resistance range is from -60°C to 280°C of the existing methyl vinyl silicone rubber Extend to -95 ℃-350 ℃, while extending the upper and lower limits of high and low temperature resistance. In addition to all the advantages of methyl vinyl silicone rubber, phenyl silicone rubber also has excellent low temperature resistance, ablation resistance, radiation resistance and self-extinguishing properties. It is one of the important materials for military industry, aerospace and cutting-edge technology. It can be used as a variety of molded and extruded products, used for cold-resistant, burn-resistant, heat-resistant aging, and radiation-resistant seals, gaskets, pipes, bars, etc. It can also be used to make various special-purpose products, such as damping materials, pressure-sensitive adhesives, etc.
