GNS & Dupont B1 GRADE FIRE RATED PU FOAM
GNS B1 FIRE RETARDANT 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.
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. Conform to fire class B1 (DIN 4102)
5. Application temperature between +5ºC to +35ºC;
6. Optimal application temperature between +18ºC to +30ºC;
7. Environmentally friendly. It contains CFC-free propellants which are harmless to the ozone layer.
