temperature of 180 ?? (instantaneous 250 ??), 100mm thick phenolic foam Flame ability up to 1 hour without being penetrated. In the direct effect of the flame with carbon, no dripping, no curly, no melting phenomenon, the surface of the flame after burning to form a layer of "graphite foam" layer, the effective protection of the foam layer structure. 2, excellent thermal insulation phenolic foam insulation board low thermal conductivity (& lt; 0.025W / m ?? K, more than 2 times for polystyrene, and polyurethane are similar), insulation, insulation excellent material. 3, anti-corrosion anti-aging phenolic foam insulation board is almost able to withstand all inorganic acids, organic acids, organic solvents erosion. Long-term exposure to the sun, no significant aging phenomenon, which has good resistance to aging. 4, low density, light weight phenolic foam insulation board density of 100 ?K / m3 or less, up to 50 ?K / m3 or so. It can reduce the weight of the building, reduce the load of the building, reduce the cost of the structure, and the construction is simple, quick and can improve work efficiency. 5, sound absorption phenolic foam insulation board has excellent sound absorption properties, open-cell foam structure is more conducive to sound absorption. 6,
