Polyurethane sandwich panels are polyurethane insulation sandwich panels for construction, also known as anti-leakage sandwich panels, polyurethane rigid foam insulation panels, polyurethane composite panels, PU panels, and the like. It is a high-efficiency and energy-saving building envelope material with wide application and great potential. It is also a new energy-saving sheet promoted and
promoted by the Ministry of Construction.
Pu sandwich panel building material is a composite sheet of polyurethane rigid foam as an insulation layer, and is mainly used for industrial kitchens, logistics storage, roofing of integrated houses, and maintenance systems.
Anti-leakage sandwich roof panel, polyurethane rigid foam insulation board, polyurethane composite board, PU board, is a popular saying of polyurethane sandwich panel. Strictly speaking, it should be a polyurethane insulation sandwich panel for construction. The national standard is GB. /T 23932-2009, the old standard of replacement is JC/T868-2000.
The product is a bimetallic surface, single metal surface, non-metal composite sheet with polyurethane rigid foam as insulation layer, which is usually used in industrial plants, logistics storage, integrated house wall and roof enclosure system.
The bonding strength of the polyurethane panels is not less than 0.09 mpa, the combustion performance of the sandwich panel reaches B1 grade, and the flexural capacity of the sandwich panel is Lo/200 (Lo is the distance between the supports), the bending load of the sandwich panel The force is not less than 0.5Kn/m2. The effective width of the sheet is usually 1000mm and the length can be customized.
