New Armaflex Rail SD insulation for railway vehicles

New Armaflex Rail SD insulation for railway vehicles

Armaflex Rail SD, manufactured by Armacell, is the first closed-cell insulation material to offer greater fire safety for railway passenger vehicles. The product is being officially launched in the UK at the Railtex exhibition, being held on 12-14 May at the NEC in Birmingham.

The completely new synthetic rubber achieves HL 2 according to the new European standard EN 45545-2, a hazard level previously unattained by flexible insulation materials.

The highly flexible elastomeric foam has very good fire properties and extremely low smoke density, achieving an excellent Euroclass Bs1 D0 rating for insulation tubes. The smoke development of Armaflex Rail SD is 10 times lower than that of a standard elastomeric insulation products and the material is self-extinguishing, does not propagate fire or produce burning droplets.

Because it is a closed-cell insulation material with low thermal conductivity and high resistance to water vapour diffusion, Armaflex Rail SD provides installations with reliable long-term protection against energy losses and condensation. As is the case with all Armaflex products, Armaflex Rail SD has a ‘built-in’ vapour barrier.

Armaflex Rail SD is available in different insulation thicknesses for a complete range of tubes, sheets, self-adhesive sheets and tape. A great advantage of the synthetic rubber, which becomes particularly apparent in the tight installation situations involved in rail vehicle con-struction, is the highly flexible nature of the material.

The homogenous, three-dimensionally linked structure of elastomeric insulation allows the sheets to be cut neatly without the release of dust or fibre particles which could pose a health threat if breathed in. The high flexi¬bility of the material also allows simple installation even on complex-shaped HVAC fittings and equipment. Application times can be further reduced by using self-adhesive sheets.
