      What is the specification of polyurethane insulation sandwich panel?

      Polyurethane insulation sandwich panel has beautiful appearance and good overall effect. It integrates load-bearing, heat preservation, fire prevention and waterproof into one, and does not need secondary decoration. It has the advantages of quick and convenient installation, short construction period and good comprehensive benefits. The product has a good cost-effective advantage, is a wide range of uses, has the potential of high-efficiency energy-saving building envelope materials, is also a new type of energy-saving board advocated and promoted by the Ministry of construction of the people's Republic of China.

      The bonding strength of the product is not less than 0.09mpa, and the combustion performance of the sandwich panel reaches grade B1. When the deflection of the sandwich panel is Lo / 200 (LO is the distance between supports), the bending bearing capacity of the sandwich panel is not less than 0.5kn/m2. The effective width of the plate is usually 1000mm, and the length can be customized. As a core material, the rigid polyurethane foam has better heat resistance. When the temperature is less than 120 degrees, the volume and strength of the polyurethane foam will not change significantly, and its thermal conductivity is smaller. When the density is 0.03kg/m3, the thermal conductivity is 63J (15cal/m.h.k).
