    Polyurethane foam can be firmly bonded with a variety of materials, so as the insulation layer of directly buried pipe almost no need to consider the adhesion of anticorrosive layer and the problem. Using high function polyether polyols and multiple methyl polyphenyl polyisocyanate as the main raw materials, under the action of catalyst, foaming agent, surfactants and so on, through chemical reaction foaming. Polyurethane shell has the advantages of light capacity, high strength, heat insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, non-water absorption, simple and quick construction and so on. It has become an indispensable material for thermal insulation, waterproof plugging, sealing and other industrial sectors such as construction, transportation, petroleum, chemical industry, electric power and refrigeration.
