B1 Class Fire Retardant PU Foam Manual Type is an one-component, high quality B1 fire retardant polyurethane foam. It is fitted with a plastic adapted head for use with a foam application straw. B1 Class Fire Retardant PU Foam has an excellent performance for installation of doors and windows, high grade fire resistance for wallboard fixing and heat insulation, can be met all fire safety requirements.
●Excellent adhesion to a wide variety of surfaces such as UPVC, masonry, brick, block work, glass, steel, aluminum, timber and other substrates (except PP, PE and Teflon);
●The foam will expand and cure by moisture in the air, strong surface after curing;
●Self-extinguish when the fire leave;
●High thermal and acoustical insulation;
●Conform to fire class B1 (DIN 4102)
●Application temperature between +5℃ to +35℃;
●Optimal application temperature between +18℃ to +30℃;
●Environmentally friendly. It contains CFC-free propellants which are harmless to the ozone layer.

Q: What factors lead to the drop of PU foam adhesion?
A: Use at low temperature, dust or oil on the bonding surface, or the quality of itself.
Q: Why does the PU foam not work well when the weather is extremely cold?A: Generally, the best application temperature of PU foam is between +18℃ to +30℃, if the temperature is too low, it will be affected.
