Phenolic Pipe Phenolic Foam Hvac Board Phenolic Foam Board For Wind Pipes

The middle layer of phenolic composite air duct is phenolic foam, and the inner and outer layers are made of embossed aluminum foil. Composite air duct is the most widely used, among which rubber plastic composite air duct, phenolic, glass magnesium, etc. are the main representatives. Composite air duct is a kind of rubber plastic composite air duct system made of rubber plastic composite insulation material, which can completely replace the traditional air duct, air valve, air outlet, static pressure box and insulation material in the air supply system of air conditioning.

Phenolic resin is the earliest industrialized plastic product in the world, and phenolic foam is just developed. Phenolic foam plastic is known as the "king of heat preservation". It was used in the heat preservation of missiles and rocket heads in the early stage. It has become the fastest developing variety of plastics in the United States, Britain, Japan and other developed countries. Phenolic foam material has good flame retardancy, low thermal conductivity, excellent sound absorption performance and long service life. Phenolic foam materials are widely used in all aspects of the national economy because of their superior characteristics, such as central air-conditioning air ducts, cold and heat transmission pipes, clean plants, shopping malls, light body fast loading rooms, cold storages, refrigerated vehicles, aircraft, ships, hotels and entertainment compartments, etc. where fire-proof, light-weight, heat preservation, sound insulation, clean and moisture-proof materials are required.

Phenolic foam plate and aluminum foil are compounded into sandwich plate, and then special flange fittings are added. The phenolic composite air duct is used for central air conditioning ventilation. The internal and external surfaces of phenolic composite sandwich panel are coated aluminum foil, and the intermediate layer is phenolic foam material. Its comprehensive performance has been greatly improved, especially in mechanical properties, such as bending resistance, compression resistance, brittleness and processing performance. It basically meets the requirements of air conditioning ventilation pipes.
