Phenolic foam is made of thermosetting phenolic resin is made from polymer organic rigid aluminum foam. 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. Phenolic insulation board with phenolic resin and flame retardant and smoke suppression agent, curing agent, foaming agent, and other additives, and other material, through scientific formula of closed groove rigid foam, phenolic insulation board in the areas of application: due to the flammable polystyrene foam and polyurethane foam, not high temperature resistant, Chiang kai-shek in some industrial developed country restrictions on use by the fire department, strict in fire protection, government departments have clear stipulation can only use phenolic insulation board. Therefore, phenolic foam material is more suitable for have strict requirements under the environmental conditions of use of high-performance materials, has a good development prospect. They are light, refractory, nonflammable, smokeless, non-toxic, not to drip of water. The wide temperature range, - 196+200℃) No shrinkage in low temperature embrittlement is the ideal insulation hvac refrigeration engineering. Phenolic foam airtight high porosity, low thermal conductivity, insulation performance is good. With resistance to water and water vapor permeability, is an ideal energy-saving insulation materials. Because of phenol with benzene ring structure, stable size, rate of 1%. And chemical stability, corrosion resistance, ageing resistance, especially in organic solution, acid, weak alkali corrosion resistance ability. Foaming process does not contain CFC foaming agent is in line with international environmental standards, its molecular structure containing hydrogen, oxygen and carbon. After pyrolysis gas avirulent insipidity, harmless to the human body and environment. Meet the national green environmental protection requirements. Through the analysis of the
insulating materials experts, starting from the practical application of the existing building insulation materials at home and abroad, the phenolic foam used in building external wall insulation materials. 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. Can play safe and energy saving effect of double insurance. Phenolic foam has good heat resistance, 25 mm thick phenolic foam plate under 1700 ℃ flame spray exposure 10 min, only slight burning without burning through, effectively prevent the spread of fire and fire. It is worth mentioning that in the fire accident, the main reason of causing casualties was the scene of the fire smoke. However, even if the phenolic foam was lit at high temperature, it will be without a drop of water under the condition of burning material and a small amount of smoke. Almost no toxic gases such as carbon monoxide. Phenolic insulation board, therefore, is the ideal of fire prevention, insulation, energy saving, green environmental protection material, phenolic foam is known as the king of the insulating material, is a new generation of insulation sound insulation material. At present, the phenolic foaming material in the developed countries has developed rapidly, has been widely used in construction, national defense, foreign trade, warehousing and storage, energy and other fields. Phenolic material accounted for 40% of the construction using acoustic foam; Japan has also established the phenolic foam popularization association, to promote the new material.
