About us

CB Frost has been trading since 1921 and has long-standing relationships with numerous railcar manufacturers/maintenance/refurb organisations, including CAF, Stadler, Alstom, Siemens, Wabtec, Hitachi, and Knorr Bremse Rail Services.

We offer an extensive range of specialist materials ideally suited to the requirements of the mass transit industry where stringent fire, smoke and toxicity standards are crucial.

Our range of specialist, high performance materials comply with rail industry standards EN45545-2, BS6853, NFF-16-101 and the LUL Safety Standards.

CB Frost supplies the full range of BISCO® cellular silicones and composites in a wide range of thicknesses. The BISCO® cellular silicones meet the most stringent industry requirements for fire, smoke & toxic fumes and extends the temperature range over which most cellular elastomers have been found to be effective. Excellent compression set values mean increased long-term reliability for sealing, cushioning and anti-vibration applications. CB Frost also supplies the full range of ARMACELL Rail SD which is highly-flexible, closed-cell insulation foam with improved fire retardant properties, low smoke generation and in-built Microban® antimicrobial protection for railway vehicles.
