Armaflex® Rail SD –Closed Cell Insulation for Increased Fire Safety in Railway Vehicles

As of this year, EN45545-2, the European Standard for fire safety in rolling stock is mandatory across Europe. With a reputation for excellence and reliability in the rail and mass transit industry, CB Frost constantly strive to provide innovative products that comply with all industry standards and as such, our range of specialist rail materials are all EN45545-2 compliant. As a result of our commitment to fire safety and protection, we are proud to work in partnership with Armacell to supply Armaflex® Rail SD insulation foam.

High-tech insulation with advanced fire protection for railway vehicles

Armaflex® Rail SD is a high-tech and innovative closed-cell thermal insulation material designed specifically for the rail industry. The closed-cell structure of this elastomeric foam-based rubber allows for improved fire-retardant properties and low smoke generation to meet hazard level 2 according to EN45545. In the event of fire, it is self-extinguishing, does not drip and does not spread flames.

In addition to its excellent fire protection properties, Armaflex® is also a highly effective material for applications such as insulation and protection for air-conditioning and refrigeration air ducts and pipes, including fittings, elbows and flanges. The closed-cell structure of the material combined with Microban® antimicrobial product protection provides an effective barrier to water vapour, reducing the risk of corrosion, mould and mildew to improve indoor air quality.

Whilst Armaflex® Rail SD resists temperatures of between -50°C and +110°C, it is unsuitable for outdoor use as it is not a UV stable material and as a result should not be exposed to direct sunlight.
