Rail and Mass Transit

Silicone Solutions in Rail and Mass Transit

The rail and mass transit industries require high performance materials that can meet the health and safety standards required to ensure passenger welfare, whilst also operating in demanding environments where they will be exposed to extreme temperatures and weathering. Viking Extrusions are experts in the rail industry with over 25 years’ experience producing silicone extrusions, gaskets and moulded parts that have been used in a wide variety of rail applications. Our ISO9001:2015 quality control system ensures consistent quality products are delivered on schedule for the duration of the project.

Specialised Materials for the Rail Industry

Our specialist grades of silicone have been specifically formulated to meet the highest global standards associated with rail and mass transit usage including: BS6853: 1999 (Category 1A conformity) •

  • BS EN ISO 4589 – 3 1996
  • NFX70-100 
  • NF F 16-101 & NF F 16-102 Classification: F0
  • EN 45545-2 R1, R7H. L1, HL2
  • EN45545-2 R22, R23. HL1, HL2, HL3 • UL94-V0

We can supply silicone rubber in both solid and sponge/foam formats to suit engineer’s needs in a wide range of rail environments. Properties of silicone rubber that lend itself to use in rail applications include:

High Temperature Resistance

Our grades of silicone rubber are formulated to operate at extreme temperatures of -60°C to +250°C making them suitable for sealing solutions in applications involving elevated temperatures such as engine gaskets, heating & ventilation systems and LED lighting/display systems.

Weather/Environment Resistant

Our silicone compounds are durable and are resistant to weathering and environmental factors such as UV, Ozone and rain. Silicone also maintains its flexibility at sub-zero temperatures. This allows seals to continue to function during adverse conditions, keeping electrical and lighting systems protected from water and dust. When designed and tested for specific applications, silicone seals can achieve IP66 ratings.

Low Smoke and Low Toxicity

Viking Extrusions’ grades of silicone have been engineered to maximise safety in the event of a fire. The materials are specially formulated to produce low levels of smoke and toxicity making them compliant with EN45545-2 regulations. Rail Applications for Silicone Products Silicone Rubber’s physical properties lend itself to be used in a variety of rail applications such as:

  • Heating, ventilation and air-conditioning (HVAC) gaskets 
  • Interior and exterior lighting gaskets 
  • Display and electrical systems gaskets 
  • Interior and exterior door seals 
  • Grommets and other components 
  • Vibration dampening 
  • Window Seals
