Polyurethane composite panels as building energy-saving insulation materials Buying polyurethane composite board panels, in Europe, America, Japan and other developed countries has been widely applied polyurethane composite sheet manufacturer, 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. Ignition time composites than pure rigid polyurethane foam slightly lower ignition time; during combustion supply polyurethane composite board panels, composite materials and PHRR AHRR than pure rigid polyurethane foams are significantly reduced. Polyether polyols, polyester polyols, foam stabilizers, catalysts, blowing agents and flame retardants and other materials by determining the ratio of the polyurethane composite plate, stir, that is made of a combination of polyether. Flame retardant solution alone prepared flame retardant foam only reach B2 level, and with the increase of the added amount of flame retardant foam physical cause performance degradation. Polyurethane composite board manufacturers _ _ Tsinghua polyurethane composite plastic sheet provided by the Engineering Plastics Co., Tsinghua ShangYinXian.
