...low flammability foam seals for indoor and outdoor use


The FERMAPOR K31 FLAME PROTECTION polyurethane foam seals fulfill the US fire safety prescriptions according to UL 94 V-2 by the independent organisation Underwriter Laboratories.

This means that foam seals with flame protection are self-extinguishing when exposed to flame. Burning sealing material, which could still cause a fire, does not drip off; the fire goes out.

The low flammability of FERMAPOR K31 FLAME PROTECTION foam seals are used both indoors and out, where the strict US fire protection stipulations for the sealing of metal switch cabinets and electronics housing are in force.

FERMAPOR K31 FLAME PROTECTION systems are also applicable in many other situations, for example, in the automotive, household appliances, lighting and packaging industries, where strict flame protection is also prescribed.
