B1 fire retardant Pu spray foam for professional using fire stop Pu Foam
B1 fire retardant Pu spray foam for professional using fire stop Pu 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.
