With the rapid development of the rail transit industry, train sealing materials must exhibit exceptional weather resistance, aging resistance, and high-low temperature durability to cope with complex operating environments. Phenyl silicone rubber, with its outstanding heat, cold, and UV resistance properties, has become an ideal material for rail transit sealing systems, widely used in door seals, window frames, and damping components.

The molecular structure of phenyl silicone rubber allows it to maintain excellent elasticity and sealing performance within a temperature range of -60°C to +250°C, preventing brittleness and cracking. Additionally, its superior ozone and UV resistance significantly outperforms traditional rubber materials, ensuring long-term outdoor durability, reducing maintenance costs, and extending equipment lifespan.

In high-speed rail and metro systems, phenyl silicone rubber is utilized in sealing and damping components, effectively reducing wind noise, enhancing cabin tightness, and improving passenger comfort. Moreover, in electrical system sealing applications, this material provides excellent electrical insulation, ensuring the safe and stable operation of onboard electronic equipment.

As the rail transit industry continues to raise safety and durability standards, the application of phenyl silicone rubber is expected to expand further, providing high-performance sealing solutions for high-speed rail, subways, and intercity trains, contributing to the advancement of rail transit technology.
