Sealing and protecting key components of rail transit systems form the first line of defense for operational safety. This critical defense is silently reinforced by high-performance foam materials.

Among them, silicone foam stands out as the "versatile protector" of rail transit. Not only does it offer exceptional sealing and waterproofing, but it also withstands extreme temperatures ranging from -60°C to 220°C. It is weather-resistant, deformation-resistant, and achieves a V0 flame-retardant rating, ensuring reliable performance even under harsh conditions. Widely used in vehicle flooring, doors, windows, and various electrical equipment, silicone foam effectively combines shock absorption and sealing functions, contributing to a smoother and more comfortable ride for passengers.Its excellent insulation and heat resistance further create a protective barrier for onboard electrical systems, ensuring stable operation throughout the journey.

Beyond sealing and protection, thermal insulation and noise reduction are equally vital for rail transit. High-performance aluminum foil PE foam, with its outstanding dual capabilities in thermal insulation and sound absorption, has become a core material for addressing these needs. It is extensively applied in critical areas such as vehicle ventilation ducts, effectively isolating external temperature fluctuations and noise to create a quiet and comfortable cabin environment.From sealing and shock absorption to flame retardancy and thermal insulation, foam materials empower every kilometer of rail transit with solid performance, safeguarding the safety and comfort of countless passengers.

Xiangyuan silicone shock-absorbing pads and high-performance aluminum foil PE foam have passed the EN45545 rail transit certification. As a professional manufacturer of rail transit materials, the company provides integrated solutions for the industry.
