Market Analysis and Forecasting Prospect of Phenolic Foam Board

In the past two years, phenolic insulation products have been widely recognized in the insulation building materials market because of its good performance and user experience of contact. Let us comprehensively analyze the advantages and prospects of phenolic products.
Chemical stability of phenolic products: Organic materials are sometimes in contact with certain solvents and chemicals during the construction and use of equipment and pipes and insulation. Therefore, it is necessary to resist chemical solvents and other properties. Phenolic foam is chemically resistant and solvent-based. It is superior to other organic foams and can be used in combination with any water-soluble glues and solvent-based glues in construction.

Thermal stability: The phenolic foam board has good thermal stability in a certain temperature range, and its continuous use temperature range from -190 °C to 200 °C before shrinkage or cracking, and the irradiation temperature of discontinuous use by hand Reports before the irradiation temperature, such as phenolic foam added with 10% glass fiber, can withstand a high temperature of 800 ° C for 1 hour without shrinkage or cracking.

Anti-combustion: The anti-burning performance of the decentralized foam mainly includes two aspects. One is the ability to prevent the flame from spreading, that is, the flame is locally generated by the heat insulating material, the flame will not be diffused and extinguished by itself; the thermal insulation property of the material itself, even in the One side of the material burns on fire, and the temperature on the other side does not rise higher, causing the fire to expand. Compared with polystyrene and polyurethane foaming, it has two characteristics: one is that there is no dripping phenomenon on fire; the other is that the surface forms a dense carbon layer on fire, which prevents further combustion of the foam.

Phenolic foam is also one of the most promising new insulation materials in the internationally recognized construction industry. Because this new material is essentially different from the usual polymer resin by the addition of flame retardant, it does not burn in the fire, does not melt, does not emit toxic fumes, and is light, non-toxic, and non-toxic. Corrosion, heat preservation, energy saving, sound insulation, low price, etc., and no freon foaming, no environmental pollution, good processability, convenient construction, its comprehensive performance is currently unmatched by various insulation materials. It is commonly used for insulation of central air-conditioning systems in high-rise and high-rise buildings such as hotels, apartments, hospitals (Hong Kong's advanced building central air-conditioning systems have been mostly converted to phenolic foam in recent years). It has undisputed comprehensive advantages for refrigeration of cold storage, cold storage, insulation for industrial pipes and equipment such as petrochemicals, building partitions, exterior wall composite panels, ceilings, sound absorbing panels, etc., and solves the fireproof performance of other organic materials. Ideal, and the inorganic material has a large water absorption rate, easy to "condense", and skin itching during construction. It is the third generation of the best insulation material for air conditioning systems and various electrical appliances.

In addition, polystyrene foaming materials have been widely used in some large and medium-sized cities in China in recent years, but due to their poor flame retardant properties and the emission of toxic gases, phenolic foaming materials will certainly replace this. , become the most competitive new building materials "target=_blank> building materials.
