Analyzing the advantages of phenolic insulation board

Phenolic foam has many excellent performance: phenol molecules contain only carbon, hydrogen and oxygen atoms, in addition to a handful of CO in the high temperature decomposition, no other toxic gases, maximum smoke for 5. 0; In addition to the strong alkali erosion, phenolic foam can also withstand almost all of the inorganic acid, organic acid and organic solvents. Phenolic plate is a new kind of non-combustible low smoke, fire insulation materials, it is made of phenolic resin in foaming agent, curing agent and other additives made of closed-cell rigid foam. It is the most prominent feature of non-combustible, low smoke, resistance to high temperature of different change. It overcomes the original type foam insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam insulation material is qualitative light, construction is convenient wait for a characteristic. Compared with other thermal insulation materials, and its service life is long, phenolic foam size stability, rate of change is small, in the use of temperature range rate was 1%. Phenolic foam with uniform obturator structure and low coefficient of thermal conductivity. 0. 025-0. 040W/( MK) The insulation performance of similar to pu, is better than that of polystyrene foamed plastic. Phenolic foam has good closed pore structure, bibulous rate is low, permeability is strong, cold when no condensation.
phenolic insulation board after installation location, can be embedded parts and closed, widely applied to improve the defects of high brittleness phenolic insulation board. Phenolic insulation board production convenient, can according to user needs in site construction; Cleaning and hygiene; Using aluminum foil composite sandwich board surface, ensuring the health of air from the duct, the frictional resistance is small, the air quality is high, because the product is called environmental duct. Because the product is made up of aluminum foil ﹢ phenolic foam ﹢ aluminum foil, and therefore has a good sound insulation, vibration resistance dimming and flame retardant, energy-saving features, to reduce the operation cost. Traditional phenolic board not only can be used for exterior insulation system, can be also prepared to act the role of surface composite insulation decoration plate, can also be used to build the traditional EPS/XPS/fire belt, PU external wall insulation system will be used for fire prevention in the curtain wall insulation insulation materials, fire door insulation materials, as well as low or high temperature fire insulation thermal insulation material. Continuous extrusion of closed pore structure caused by the plate density, water absorption, coefficient of thermal conductivity and permeability are lower than other types of plank, widely recognised as one of the best on the market at present of insulating material.
