Phenolic board material is a polymer organic rigid aluminum foam products, foam thermosetting phenolic resin. Phenolic board it has a lightweight, fire and met the fire is not burning, smoke-free, non-toxic, non-drip, surrounded by a wide operating temperature. Description (-196 ~ + 200 ℃), low temperature environment does not shrink, not brittle characteristics. Phenolic board known as the "King of insulation material" reputation, is a new generation of thermal insulation materials fire. Because phenolic board obturator rate, the low thermal conductivity (can be less than 0.030w / mk), good insulation properties, and has a certain resistance to water and water vapor permeability, is a good thermal insulation material, it is warm through refrigeration engineering ideal insulation. Since phenol having a benzene ring structure, dimensional stability, rate of change of <1%. And the chemical composition and stability, corrosion aging, especially the ability of organic solvents, acid, alkali corrosion. In the production process in the foam blowing agents do not have freon line with international environmental standards, and its molecular structure containing hydrogen, oxygen, carbon, when the pyrolysis gas spilled toxic, tasteless, the human body, are harmless to the environment, in line with the national environmental protection requirements. Therefore, phenolic board is ideal fire protection, thermal insulation, energy-saving, environmentally friendly and beautiful green insulation material. At present, the rapid development of phenolic board phenolic foam in developed countries, has been widely used in construction, defense, trade, storage, energy and other fields. US construction industry with noise insulation foam, phenolic materials accounted for 40%; Japan phenolic board has been established to promote the popularity of this new material association. Phenolic board or internationally recognized building in the ranks of the most promising of a new type of insulation material. Because this new material and generally rely on adding flame retardant polymer resin materials have been essentially different, does not burn in the fire, does not melt, it will not emit toxic fumes, and a lightweight, non-toxic, non- corrosion, insulation, energy-saving, noise, low cost, etc., and without Freon foam, no pollution, good processability, easy construction, and its overall performance is unmatched variety of insulation materials. Yuncheng Phenolic insulation board price bwb-370 universal in hotels, apartments, hospitals and high-rise buildings and other senior central air conditioning system insulation (senior building central air conditioning system in Hong Kong in recent years has been most use phenolic board material). Refrigeration, cold storage and cold for petrochemical and other industrial piping and equipment insulation, building walls, exterior composite panels, suspended ceiling, acoustic panels, which are undisputed comprehensive advantages to solve other organic material fire performance is not ideal, large water absorption of inorganic materials, easy "condensation", the construction of skin itching and other issues, is the air conditioning system, the third generation of the best variety of electrical insulation materials. The main technical parameters: bulk density 40-100kg / m3; 20-200mm thickness thermal conductivity 0.022-0.030w / mk flammability rating B1-A2 smoke density rating <5 Operating temperature -196 ~ + 200 ℃ phenolic board has the following excellent performance: 1, phenolic board has a uniform closed cell structure, low thermal conductivity, good insulation properties, polyurethane rather better than polystyrene foam; 2, under the direct action of the flame with a knot of carbon, no drip, no curling, no melting phenomenon, the flame burned layer formed on the surface "graphite foam" layer, effectively protect the foam structure within the layer, anti-flame penetration time of up to 1 hour; 3, large temperature range suitable for the short term in -200 ℃ ~ at 200 ℃ use, long-term use at 140 ℃ ~ 160 ℃, than polystyrene foam (80 ℃) and polyurethane foam (110 ℃); 4, phenolic molecules containing only carbon, hydrogen, oxygen atom, by pyrolysis, in addition to small amounts of CO gas, but will not produce other toxic gases, smoke density maximum of 5.0%. 25mm thick phenolic board at 1500 ℃ withstand flames 10min after injection, only a slight carbonation but not burning surface wear, neither fire nor will emit smoke and toxic gases; 5, phenolic board in addition to alkali corrosion may be outside Almost all resistant to inorganic acids, organic acids, organic solvents erosion. Long-term exposure to sunlight, no significant aging phenomenon, which has good resistance to aging; 6, has a good closed-cell structure, low water absorption, anti-vapor infiltration, when used as insulation purposes (cold), condensation does not occur; 7, dimensional stability, low rate of change in the operating temperature range of the dimensional change of less than 4%; 8, low cost phenol board, only about two-thirds of the polyurethane foam.

Throughout the insulation market, insulation materials commonly used mainly polystyrene board, extruded polystyrene board, polyurethane foam. The biggest problem the existence of these insulation materials, fire performance is poor, even Mars welding produced, but also make these insulation materials fire. These insulation materials when burned, produces a large number of financial drop objects and toxic fumes, not only caused massive environmental pollution, caused great inconvenience to the rescue of fire, but also endanger the lives of residents and firefighters. To this end, September 25, 2009, the Ministry of Housing and Urban-Rural Development jointly developed a "civil insulation systems and external decorative fire Interim Provisions", the article states: civil height greater than or equal to 100 meters, the other civilian When the building is greater than or equal to 50 meters and 24 meters above the curtain wall construction, the combustion performance of insulation materials should be Class A; when smaller than the height of the fire buffer zone should be established. This gives domestic manufacturers of phenolic huge market, the country has been put into operation or under construction in phenolic board more than a dozen manufacturers.
