Phenolic insulation board characteristics what _ phenolic insulation board, phenolic board manufacturer
phenolic insulation board is often referred to as phenolic foam insulation materials. Phenolic foam based on phenolic resin and flame retardant and smoke suppression agent, curing agent, foaming agent, and other additives, and other material, through scientific formula of closed groove rigid foam.
1, 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 foam case of non-combustible, combustion 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.
2, excellent insulation performance, low thermal conductivity, < 0. 025W/m× K for more than 2 times of eps, close to pu) , good for heat preservation, heat insulation materials;
3, corrosion resistant, anti-aging, almost all inorganic acid, organic acid, organic solvent resistance of erosion. Long-term exposure to sunlight, no obvious aging phenomenon, thus has good aging resistance;
4, small density, light weight, the density of phenolic foam is below 80 ㎏ / m3, can achieve about 50 ㎏ / m3. Can reduce the building self-respect, reduce the load of the building, reduce the cost of the structure, and the construction is simple, fast, and can improve the work efficiency;
5, the sound absorption performance: composite phenolic insulation board with excellent sound absorption performance, open groove bubble structure is more advantageous to sound absorption;
6, environmental protection: rock wool, glass wool has harm to environment and people, polyurethane, polystyrene combustion heat will break out of the toxic gas such as carbon monoxide. The phenolic foam with cfc-free foaming technique, no fiber, conform to national and international environmental requirements.
