B2 fire rating pu foam fire resistant retardant pu polyurethane foam
B2 fire rating pu foam fire resistant retardant pu polyurethane foam is a one-component, self-expanding, ready-to-use, Multi-purpose Polyurethane foam. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation. It will stop burning when there is no fire contact. It is environmental friendly as it does not contains any CFC materials.
