Because polyurethane sheet has excellent insulation properties, to achieve the same insulation under the requirements of the building can reduce the thickness of the external structure, thereby increasing the indoor area. Resistance to deformation tough polyurethane sheet plant, easy to crack rigid polyurethane insulation board manufacturer, finishes stable and safe. Polyurethane composite panels as building energy-saving insulation materials, in Europe, America, Japan and other developed countries has been widely used, a penetration rate of 80%, used in China is less than 10%. Polyurethane sandwich panels as an excellent energy-saving insulation materials, its excellent thermal insulation, fire protection, thermal insulation properties and can provide efficient solutions to solve China's energy consumption crisis. Rigid polyurethane insulation sheet | Tsinghua plastics | rigid polyurethane sheet provided by the Engineering Plastics Co., Tsinghua ShangYinXian. ShangYinXian Tsinghua Engineering Plastics Co.
