Phenyl silicone rubber is a new type of silicone rubber material developed internationally to meet the increasing requirements for high and low temperature resistance. (A3) is formed by co-ring-opening polymerization modification with methyl mixed ring (DMC) and vinyl ring (VMC). Its temperature resistance range is from -60℃ to 280℃ of existing methyl vinyl silicone rubber Expanded 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 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 various molded and extruded products for sealing rings, gaskets, pipes, bars, etc. It can also be used to make various special-purpose products, such as damping materials, pressure-sensitive adhesives, etc.
Basic classification of phenyl silicone rubber
Low Phenyl Silicone Rubber
When the phenyl content is 5-10% (the ratio of phenyl to silicon atoms), it is generally called low phenyl silicone rubber. At this time, the hardening temperature of the rubber is reduced to the lowest value (-115 ° C), which makes it have the best low temperature resistance. performance, still has flexible elasticity at -100 ℃.
Medium phenyl silicone rubber
With the increase of phenyl content, the rigidity of the molecular chain increases, and its crystallization temperature increases instead. When the phenyl content is 15-25%, it is generally called medium phenyl silicone rubber, which has the characteristics of flame resistance.
High phenyl silicone rubber
When the phenyl content is more than 30%, it is generally called high phenyl silicone rubber, which has excellent radiation resistance. Phenyl silicone rubber is used in applications requiring low temperature resistance, ablation resistance, high energy radiation resistance, heat insulation, etc.
