As urban rail systems expand, the demand for safety, durability, and airtightness in train design is growing rapidly. Phenyl silicone rubber putty, with its superior flexibility, heat resistance, and environmental adaptability, has become a vital material in advanced sealing systems, widely used in subway cars, track joints, and equipment enclosures.

Unlike traditional rubber, this material remains soft and pliable under extreme temperatures, resisting cracking or degradation. It offers excellent resistance to oils, ozone, and UV rays, making it suitable for long-term exposure to both outdoor and underground conditions.

Its easy application and strong adhesion allow it to bond well with metals, glass, and composites, forming a reliable barrier against moisture, dust, and corrosive substances. As urban transit evolves toward smarter, more tightly sealed systems, phenyl silicone rubber putty is expected to see expanding applications in advanced infrastructure.
