 —Polyurethane sandwich panel(50/75/100/150/200mm)

1. Polyurethane sandwich panel is a bimetallic, single-metal, non-metal composite sheet made of polyurethane rigid foam as insulation layer. It is usually used in industrial plants, logistics storage, wall and roof enclosure systems for integrated houses. The bonding strength of the polyurethane sandwich panel is not less than 0.09MPa, 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.
