What advantages of phenolic board?
phenolic plate made of phenolic foam, phenolic foam is a macromolecule organic rigid aluminum foil foam products, is composed of thermosetting phenolic resin foam.
2, the advantages of phenolic board
1, excellent fireproof performance: phenolic foam insulation board with phenolic insulation board meet fire non-combustible, combustion performance up to A level, the highest working 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 to form a 'graphite foam layer, foam structure within the effective protective layer.
2, excellent insulation performance, low thermal conductivity (phenolic foam insulation board < 0. K. 025 w/m, more than twice for polystyrene, close to pu) Excellent for insulation, heat insulation materials;
3, corrosion resistant, anti-aging, phenolic foam insulation board can 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, density of phenolic foam insulation board as below 100 ㎏ / 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: phenolic foam insulation board has excellent sound absorption performance, open groove bubble structure is more advantageous to sound absorption;
6, environmental protection: phenolic insulation board with cfc-free foaming technique, no fiber, conform to national and international environmental requirements.
