Phenolic foam insulation board combustion resistance testing

by:Ventech     2020-11-26
Phenolic foam insulation board combustion resistance mainly include two aspects, one is the ability to prevent the spread of flame, the partial adiabatic materials produce flame, the flame itself will not spread out; Second, adiabatic performance of material itself, even in burning material side, on the other side of the temperature rises higher and cause fire. Compared with polystyrene foam, polyurethane foam has two characteristics, one is on fire with no dripping phenomenon, 2 it is in the burning compacted carbon forms on the surface, it is to prevent further combustion of the bubble.
