Phenyl silicone rubber, as a high-performance specialty rubber material, is demonstrating significant application value in high-end manufacturing sectors such as aerospace and nuclear energy equipment due to its unique performance in extreme environments. By introducing phenyl groups into the polysiloxane backbone, this material significantly enhances low-temperature resistance and radiation resistance while maintaining the excellent thermal stability of traditional silicone rubber.

Research shows that phenyl silicone rubber maintains good elasticity even at extremely low temperatures of -100℃, with its low-temperature embrittlement point significantly lower than conventional silicone rubber. Meanwhile, its radiation resistance reaches 1×10^7 Gy, far exceeding the tolerance limits of ordinary rubber materials. With tensile strength of 7.5-9.5 MPa, it retains over 80% of its original performance after 500 hours of aging tests at 200℃.

In the aerospace sector, phenyl silicone rubber has become a critical material for deep space exploration equipment sealing systems. Measurement data indicates it maintains perfect sealing performance in extreme temperature alternating environments ranging from -110℃ to 180℃. In the nuclear energy equipment field, the material is widely used in critical applications such as nuclear power plant instrument seals and cable sheathing in radioactive environments.

Industry experts note that with continuous development of new material technologies, phenyl silicone rubber will play a crucial role in more extreme environment applications, providing important material support for the innovative development of high-end equipment manufacturing industry.
