Phenolic insulation board is introduced



polyurethane material porosity structure stability, is essentially closed pore structure, not only the heat preservation performance is good, and freeze resistance, sound absorption. The average life expectancy of hard foam polyurethane insulation structure, under the condition of normal use and maintenance, can reach more than 30 years. Can do in the life of the structure under the condition of normal use, in a dry, wet and electrochemical corrosion, and because of the insects, fungi or algae growth or due to external influence, such as the destruction of the rodents are not damaged.

excellent fireproof performance: the organic heat preservation material such as polyurethane and polystyrene, after burning, can produce smoke and poisonous, easy to cause death, fire fighting and also increase the difficulty. And phenolic non-combustible insulation board in the fire, burning performance up to A level, the highest temperature of 180 ℃ ( Allow instantaneous 250 ℃) , the 100 mm thick phenolic foam flame resistance can be more than 1 hour and not get through. The flame with a knot under the direct effect of carbon, without dripping, curly, no melting phenomenon, after the flame surface forming a layer & other; The graphite foam & throughout; Foam structure layer, the effective protective layer
