Product Description

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.


PRODUCT FEATURES

1. 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);
2. High thermal and acoustical insulation;
3. Very good filling capacities;
4. High Bonding strength with B2 fire class in DIN4102 part 2;
5. Application temperature between +5ºC to +35ºC;
