As industries such as high-voltage power systems, nuclear energy, and aerospace demand materials with enhanced safety and long-term reliability, hydroxyphenyl silicone rubber is emerging as a promising solution. With its unique molecular structure and high phenyl content, it delivers exceptional radiation resistance, thermal stability, and electrical insulation—making it ideal for critical sealing and encapsulation applications.

By introducing phenyl side groups into the polysiloxane backbone, hydroxyphenyl silicone rubber significantly improves oxidative and radiation stability. Laboratory tests show that its mechanical properties retain over 85% after exposure to gamma rays or electron beams, outperforming standard silicone or fluororubber. Moreover, the presence of hydroxyl groups increases its reactivity, enabling advanced processing techniques such as liquid injection molding and precision compression molding.

In applications like HV transformer insulation shells, nuclear reactor seals, and aerospace vibration dampers, this material ensures long-term operation across a wide temperature range (-60°C to +250°C). It also offers excellent dielectric strength and minimal compression set, contributing to system reliability and safety.

Recent development trends focus on enhancing transparency, reducing modulus, and improving adhesion to suit multi-functional integration under harsh conditions. Hydroxyphenyl silicone rubber is poised to become a key material in the future of high-performance electrical and radiation-shielding solutions.
