Phenolic foam is also the most promising new type of insulation material in the internationally recognized construction industry. It does not burn in the fire, does not melt, does not emit toxic fumes, and is light, non-toxic, non-corrosive, and heat-insulating. Energy-saving, sound-insulating, low-cost and other advantages The phenolic board is a closed-cell rigid foam made of phenolic resin with flame retardant, smoke suppressant, foaming agent, curing agent and other additives. Phenolic foam is a polymer organic hard aluminum foil foam product. It is known as the “king of insulation materials†and is a new generation of thermal insulation and fireproofing materials. It is light, fireproof, non-flammable, non-flammable, non-toxic, and non-toxic. No dripping and other characteristics. The fire performance of the phenolic insulation board is B1 grade flame retardant material. The high-density phenolic foam with inorganic filler can have an oxygen index of 60-70 and a combustion grade of A. The insulation layer is made of phenolic foam and is used in combination with other materials for building insulation. It can basically reach the national fire protection standard A level, and fundamentally eliminate the possibility of external insulation fire. The temperature range is -250°C～+150°C. Phenolic insulation boards have a wide temperature range. Phenolic foam is a safe, green new energy-saving building material.
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 the 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 cost, 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). According to incomplete statistics, the annual demand for ventilation pipe sheets in China is more than 50 million square meters. The market demand is large and the application range is wide. However, the market share of phenolic foam sandwich panel air ducts is less than 5%. The application of materials provides an extremely broad market space, which is both an opportunity and a challenge.
However, due to the maturity of product technology, the recognition of the architectural design department, the matching of installation technology, the specification of product and installation standards, people's usage habits, and price, etc., it will affect the marketing speed of the product. Turning huge market potential into real market demand, making phenolic foam sandwich panel ducts the leading product of central air-conditioning ducts. At present, there are more than a dozen phenolic foam manufacturers in China that have been put into production or under construction, such as Xiamen Gaote. High-tech materials company is an early manufacturer of phenolic products. Relevant experts pointed out that while further improving the production technology of phenolic foam sandwich panel duct products and meeting market demand, we should speed up the development of special equipment for phenolic foaming, increase foaming yield and reduce production costs. Relevant departments should set up industry management as soon as possible. Coordinate organizations to develop national standards for phenolic foam ducts and maintain normal competition in the market.
