FP311 INTUMESCENT GRAPHITE

Bostik FP 311 Intumescent Graphite is a high specification formulation designed to prevent the spread of fire, smoke
and gasses through openings in fire rated walls and floors. Bostik FP 311 Intumescent Graphite is a single component,
waterbased, fire retardant sealing compound which contains a high concentration of heat expanding graphite material. Bostik FP 311 Intumescent Graphite expands when it is subjected to fire and closes openings around combustible pipes (e.g. PVC) or metal pipes fitted with combustible insulation. Thermal activation takes place at 150°C when the material will intumesce to prevent the
spread of fire, smoke and gases through openings up to 4 hours. 

Bostik FP 311 Intumescent Graphite offers a very good sound insulation.
