        THE RIGID FOAMED POLYURETHANE >>

        Rigid polyurethane foam is one of the synthetic materials developed in the modern international plastic industry. Its characteristic is through changing the structure of the molecules in the link, can do all kinds of modified significantly, and under the condition of the change process formula, can be obtained from soft to hard, different density and properties of foam plastic products, and spray forming the site construction is simple, the proportion of small, high strength, low thermal conductivity, good insulation effect, application range, almost penetrated into the national economy departments, especially in the refrigerators, freezers, refrigerated trucks, refrigerated ships, garage door, water heater, a container, cold storage building, constant greenhouse, pipeline heat insulation, sound insulation, shockproof, lightweight structural purposes. Therefore, polyurethane foam insulation materials occupy an important position in the world plastics industry.

        Haiyan company main products are applicable to the production of polyether polyols and catalysts, stabilizing agent, foaming agent as raw materials, such as the regulations made under the technological conditions of HY series of rigid polyurethane foams portfolio polyether (hereinafter referred to as materials) group A and group A with more and more methyl phenyl isocyanate (hereinafter referred to as the group B material) response of rigid polyurethane foam plastics.
