Sealing Solutions for the Rail Industry – Metal Reinforced Silicone Profiles

As specialists in the supply and conversion of a comprehensive range of silicone products, we regularly provide extruded silicone profiles for the rail and mass transit industries, including the development and manufacture of specialist, bespoke products.

Needless to say, the specifications of sealing solutions for the rail industry are unique – not only are all materials, profiles and products required to comply with a number of industry safety standards, but they must also be able to withstand the vibration, shock, abrasion, range of temperatures and risk of fire that exist as a result of high-speed rail travel. Whilst the requirements of our rail clients can be highly complicated, we always work alongside them to devise sealing solutions where the end product can be as simple as possible. Our metal reinforced silicone profiles are certainly a good example of this.

As rail stock will be subject to vibration and shock when travelling at high speeds, ensuring that sealing profiles are effectively fixed is vital. A reliable solution for a profile to be fixed to an end product is to reinforce the profile; by using metal reinforcement to strengthen the fixing point of a silicone profile, this removes the need for tape, adhesive or any separate fixing plate. As a result, the overall design of the end product will be kept as simple as possible.

At CB Frost, our metal reinforced silicone profiles contain a core of stainless steel wire which is embedded within the profile during the extrusion process. This adds rigidity to the profile to ensure a guaranteed fit to the end product, with easier installation.

In order to conform with the safety regulations of the global rail sector, our metal reinforced profiles conform to the following fire safety standards:

  • EN45545-2 – European Union Standard Fire Testing
  • DIN5510-2 – German Standard Fire Testing
  • NF F16-101 – French Standard Fire Testing
  • BS6853 – British Standard Fire Testing
  • NFPA130 – French Standard for Fixed Guideway Transit and Passenger Rail Systems
  • GOST 12.1.044-89 – Russian Standard Fire Testing

Key uses of metal reinforced silicone edge trims

The properties of metal reinforced silicone profiles mean that they are well suited for a number of applications within the rail and mass transit industry. They are commonly used as sealing solutions for:

  • Windows
  • Door systems
  • Floors
  • Ceilings
  • HVAC systems
  • Walls
  • Lighting systems
  • Luggage compartment racks

Standard reinforced profiles

In addition to developing bespoke metal reinforced profiles, we are also able to offer a selection of several standard profiles. The tooling for said profiles is owned by CB Frost, so our customers are completely free to utilise these in their projects.
