Phenolic board Description: A grade fireproof board are thermoset phenolic foam insulation, fire does not burn, does not shrink, no distortion, no drip, does not have a flame propagation. Its high level of flame retardant, fire performance, with a fire burning only one carbide layer is formed on its surface, burning, distortion does not occur. Compared to the commonly used insulation materials, the biggest advantage is flame retardant, high temperature dimensional stability, no shrinkage, no melt drip, anti-flame penetration. It can be made into wall insulation board, shell and all kinds of special products, a lightweight construction and convenient. Phenolic board has the following advantages: first, safety, excellent smoke-free, non-toxic, fire performance. The second effect is good insulation, thermal conductivity between 0.022 to 0.3. The third is that it has good air permeability, permeability in buildings is important, breathable material used in construction, the mist and frost will not produce the phenomenon. The fourth is its environmental performance, the material can be recycled, not cause secondary pollution. Phenolic board is a new flame retardant, low smoke and fire insulation materials, thermal conductivity is only 0.023W / mk or so, the most prominent feature is flame retardant, low smoke, high temperature rambling. It can be made into wall insulation board, shell and all kinds of special products, a lightweight construction and convenient. Phenolic insulation board often referred to as phenolic board. Phenolic board is a phenolic resin and flame retardant, smoke suppressant, curing agents, blowing agents, and other additives, and other substances, closed-cell rigid foam made by scientific formula. Phenolic board applications: Widely use phenolic board, it applies to large cold storage, storage tanks, ships and a variety of pipe insulation and construction. If used in fire demanding factories, mines and machinery and equipment, to better highlight its flame retardant, low smoke, high temperature rambling characteristics. Such as: ships, ships, trains, armored vehicles, insulation and paper, chemical, pharmaceutical and other areas. Phenolic fire does not melt at high temperatures drop, does not soften, low smoke, non-proliferation of flame resistance, flame penetration, the system up to the national A-class fire safety standards, and has good thermal insulation effect, the excellent fire performance and good energy savings rolled into one, suitable for exterior insulation. Because polystyrene foam and polyurethane foam are flammable, not high temperature, in some industrialized countries, were being restricted fire department, fire safety demanding places, government departments have been expressly provided only with phenolic board and phenolic sandwich board. Thus, phenolic board insulation board is more suitable for high-performance materials have under demanding environmental conditions, and has good prospects for development. Other needs such as fire insulation requirements of the building steel plants, large industrial plants, activities room, cold storage, clean shop, building and floor, temporary housing, stadiums, supermarkets. Phenolic board excellent performance: a superior fire performance: polyurethane and polystyrene insulation and other organic materials, combustion will produce smoke and toxic, easy to cause death, but also increase the difficulty of the fire. The phenolic board insulation board in a fire burn, burn up to A-level performance, maximum use temperature of 180 ℃ (allows instantaneous 250 ℃), 100 mm thick phenolic board insulation board anti-flame capacity of up to 1 hour or more without being penetrated . Carbon has a knot under the direct effect of the flame, no drip, no curling, no melting phenomenon, the surface layer of the foam structure "graphite foam" layer after layer to effectively protect the flame burning. Two excellent insulation properties: low thermal conductivity (<0.025W / m × K, more than twice as polystyrene, polyurethane similar), for thermal insulation of fine materials; 3 corrosion aging: resistant to almost all inorganic acids, organic acids, organic solvents erosion. Long-term exposure to sunlight, no significant aging phenomenon, which has good resistance to aging; small 4-density, light weight: the density phenolic board material for 80㎏ / m3 or less, up to about 50 kg / m3. Reduce the weight of the building, reducing the load of the building, reducing the cost structure, and the construction is simple, fast, can improve work efficiency; 5 sound absorption properties: Phenolic board has excellent sound absorption performance, open-cell foam structure more conducive sound absorption; 6 green: rock wool, glass wool on the environment and people hurt, polyurethane, will decompose cyanide, carbon monoxide and other toxic gases when burning polystyrene heat. The phenolic foam board insulation board with CFC-free technology, no fiber, in line with national and international environmental requirements. Phenolic board Features: 1, A-class fire performance phenolic board insulation, fire-resistant, fire safety systems meet the national standard A-level, the possibility of external insulation to prevent fires from fundamentally temperature range of -250 ℃ ~ + 180 ℃. 2, thermal insulation effect is prominent phenolic board has good insulation properties, thermal conductivity of about 0.035W / (m? K), far below the current market common inorganic, organic wall insulation products, can achieve higher energy savings. 3, solvent and solvent phenolic board, is currently the only direct brushing solvent-based paint insulation materials. 4, is widely used not only for traditional exterior insulation and finish systems can also be produced with the veneer layer composite board insulation decorative integration can also be used to build a conventional EPS / XPS / PU Fire Barrier external wall insulation systems, used for fireproof insulation materials inside the walls, fire door insulation materials, insulation and fireproof material low or high temperature applications.
