The FERMAPOR K31 FLAME PROTECTION polyurethane foam gaskets meet the US fire safety requirements according to UL 94 V-2 flammability rating by the independent organization of Underwriter Laboratories.
This means that foam gaskets with flame protection are self-extinguishing when exposed to flame. Burning sealing material, which could still cause a fire, does not drip, instead the fire goes out.
The low flammability of FERMAPOR K31 FLAME PROTECTION foam gaskets are used both indoors and outdoors, where the US fire protection stipulations for the sealing of metal switch cabinets and electronics housing are in force.
FERMAPOR K31 systems with flame protection are also requested in many other industries, for example, automotive, household appliances, lighting and packaging.
