Industry Standards

Our catalogue of cellular silicone insulation materials for the rail industry complies with rail industry standards including BS6853:1999, EN45545-2, NFF-16-101 and the LUL (London Underground) safety standards, you can be confident that all roll stock and converted materials conform to industry legal regulations.

Manufacturing Capabilities

All rail sector materials are available as roll stock, or can be cut into gaskets, washers and strips (tape). We can also manufacture fabrications and bonded gaskets by joining different materials together to suit specific applications. We have recently invested in a new high-speed die cutting and kiss-cutting press, allowing us to increase our manufacturing capabilities, whilst maintaining pin-point accuracy.

Wind Turbines


CB Frost's sealing materials are effective for the energy sector as they prevent dust or moisture from seeping into a component. Any seepage could cause components to suffer from damage or even failure.

Street Light Sector


Effective sealing materials for lighting are essential for preventing dust or moisture from seeping into a lighting component and damaging it, often resulting in costly replacement fees.

Automotive Sector


Rubber is a key material in the automotive industry due to its advantageous properties including a high level of flexibility and low compression set when faced with extreme low and high temperatures.

Military Sector


Synthetic rubbers were originally used in military applications as military vehicles developed rapidly after WW1. This has not changed today, we at CB Frost are extremely proud to be an approved supplier for the Ministry of Defence. 

HVAC Industry


CB Frost's medium density, fire safe, UV and ozone resistant silicone sponge is ideally suited for HVAC systems.

Manufacturing Excellence

Ahead of our competition

In 2018, EN45545-2, the European Standard for fire safety for the rail industry became mandatory across Europe, replacing the old national standards to provide improved safety assurances throughout the continent. At CB Frost, we were ahead of the curve and all of our rail materials were EN45545-2 compliant before this standard became mandatory. C.B. Frost pides itself on working with our suppliers and partners, and always aim to be ahead of all industry changes.

Innovation solutions

As specialists in insulation materials and solutions for the rail and mass transit industry, we understand the challenges faced. Just two examples of CB Frost innovations are our introduction of a new EN45545-2 compliant lightweight rail material, CBF SIL-V0, and our metal reinforced silicone profiles.

CBF SIL-V0 is a versatile, lightweight, closed-cell material, which is highly versatile and adaptable for a number of applications within the rail sector, including light seals, HVAC seals, electrical enclosure seals, gap fillers, LCD displays, and anti-vibration.
