Stopfire has been proven to be one of the best cellular foams in an impregnated flexible polyurethane resin. It is considerably flame resistant obtaining the fire reaction class 1 in many conventional tests. Stopfire does not burn, melt or drip. When subjected to heat, flammable volatile products may disperse but the shape of fo am does not change and the mineral structure remains the same. Stopfire is also available in an adhesive version with water-based acrylic glue.
Stopfire is excellent for all types of heat and sound insulation, particularly in areas that require CL1/M1 certification. Recommended for engine compartments, generators, ventilation systems, compressors, boilers etc.
