Polyurethane sandwich panels are widely used in large industrial plants, cold storage, garages, mobile homes, exhibition halls, stadiums, shopping malls, airports, power plants, villas, hospitals, high-rise office buildings and other areas of the formation and Buying polyurethane composite board panels, due to excellent The insulation properties are mainly used in industrial and civil buildings roof and wall. Rigid polyurethane fire retardant, high temperature. After adding a flame retardant polyurethane polyurethane composite sheet manufacturer, is a self-extinguishing flame retardant material supply polyurethane composite sheet, its softening point can reach 250 degrees Celsius, will appear only at a higher temperature decomposition: Another , the polyurethane is formed upon combustion of coke on the surface thereof the foam, which help isolate the coke layer below the foam. Can effectively prevent the spread of flame. Further, the polyurethane does not produce harmful gases at high temperatures. Polyurethane composite sheet, Tsinghua engineering plastics, polyurethane composite sheet provided by the Engineering Plastics Co., Tsinghua ShangYinXian. ShangYinXian Tsinghua Engineering Plastics Co. (www.tyqhgc.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
