Phenyl silicone rubber, with its excellent heat resistance and electrical insulation, has become an indispensable material in the rail transit industry. Metro and high-speed trains are exposed to extreme conditions such as high heat, electrical arcing, and mechanical stress during operation. Phenyl silicone rubber, with outstanding thermal stability, can withstand temperatures above 250℃ without performance degradation, ensuring the safe operation of electrical components and cables. Its flexibility and tear resistance make it particularly effective in cable sheaths, insulating gaskets, and onboard electrical equipment. Compared to conventional high-temperature rubbers, phenyl silicone rubber offers longer service life and reduced maintenance needs, providing more efficient and reliable protection. With the advancement of smart rail systems, its applications in next-generation electrification systems will further expand, helping the industry achieve higher safety standards and sustainable growth.
