Integrally molded polyurethane lined with polyurethane foam sponge lining it refers to what is it? What kind of features it does? This is a lot of people do not know, it refers to the production line at the factory specializing in the production, to polyurethane foam lining material for the core material. Sponge box lined with polyurethane foam manufacturers about what characteristics? 1. widely used in temperatures between normal temperature -40- + 90 ℃, high dimensional stability, good weather resistance and chemical stability. Low moisture absorption, air tightness polyurethane sponge lining also has a low hygroscopicity. Sponge packaging manufacturers which means that it describes have a longer life than other insulation materials, which can be more effectively exert its excellent heat insulating performance. The building has excellent performance concrete, clay brick, metal, wood, rubber and glass paste and other powerful or complex features, and can be easily cut type, installed. Good fire performance by adjusting the formula, it can meet the domestic and international standards requirements. It does not have melt dripping phenomenon as EPS or XPS like material, and a polyurethane sponge lining material in the combustion process, will form a protective layer to inhibit coke combustion spread. Also tell sponge metal packaging manufacturers veneer can further enhance its flame retardant properties. High strength with high compressive strength, adhesion and shear strength, Shenzhen-sponge plant can be adapted to the more normal contact with the base material deformation without cracks, hollowing phenomenon. Low density, low thermal conductivity under normal circumstances, the density of rigid polyurethane foam panels 35-40 kg / m3. Non-toxic, non-irritating and non-biological parasitic polyurethane foam lining toxic, non-irritating, safe and convenient operation. In addition to its non-parasitic organisms, not parasite class, it will not nourish parasites. Shaw Health Mobile: 15818793630 QQ: 2737838854
