Phenyl silicone rubber is a high-performance silicone rubber material composed of monomers such as styrene and dimethylsilane. It has found widespread application in numerous industrial fields due to its exceptional high and low temperature resistance.

The high temperature resistance of phenyl silicone rubber is primarily attributed to the presence of siloxane groups. Siloxane groups exhibit high chemical inertness and thermal stability, maintaining good elasticity and physical properties even at high temperatures. This makes phenyl silicone rubber an ideal choice for high-temperature sealing and insulating materials in automotive manufacturing, aerospace, and electronic and electrical fields.

Additionally, phenyl silicone rubber possesses outstanding low-temperature resistance. The introduction of phenyl groups on the side chains of polysiloxanes disrupts the regularity of the dimethylsiloxane structure, significantly lowering the crystallization temperature of the polymer and thereby expanding its low-temperature application range. Low phenyl silicone rubber (with a phenyl content of 5-15%) retains good flexibility at -115°C, becoming an indispensable elastic material in extremely low-temperature environments.

Furthermore, phenyl silicone rubber exhibits high electrical insulation and radiation resistance, making it widely used in power, electronics, and military industries. As the phenyl content increases, the flame retardancy and radiation resistance of the silicone rubber gradually enhance, but its cold resistance decreases. Therefore, when selecting phenyl silicone rubber, a balance must be struck based on specific application scenarios.

In summary, phenyl silicone rubber plays an irreplaceable role in numerous industrial fields due to its exceptional high and low temperature performance, as well as its good electrical insulation and radiation resistance.
