Rail transit systems operate in complex environments where seals and dampers must endure temperature swings, vibration, and oxidation. Phenyl silicone compounds deliver excellent performance in such conditions, thanks to their superior flexibility, ozone resistance, and heat stability.

Compared to standard silicone rubber, phenyl compounds operate reliably from -60°C to 250°C. The phenyl groups in their molecular chain enhance thermal oxidative resistance, significantly extending service life.

As railway systems advance toward greater speed and automation, phenyl silicone compounds will become essential materials for ensuring safety and reliability.
