What are the applications of polyurethane insulation sandwich panels?

Polyurethane sandwich panel integrates load-bearing, heat preservation, fireproof and waterproof, and does not need secondary decoration. It is quick and convenient to install, short construction period and good comprehensive benefit. It is a new type of energy-saving panel advocated and promoted.

Anti-seepage sandwich roof panels, polyurethane rigid foam insulation panels, polyurethane composite panels, and PU panels are popular terms for polyurethane sandwich panel. Strictly speaking, it should be a polyurethane insulation sandwich panel for construction, which meets the national standards.

The use of polyurethane insulation panels

Polyurethane sandwich panels are double-metal, single-metal and non-metal composite panels with polyurethane rigid foam as the insulation layer. They are usually used in wall and roof enclosure systems of industrial plants, logistics warehouses, and integrated houses.

The bonding strength of the polyurethane insulation panels are not less than 0.09MPa, the combustion performance of the sandwich panel reaches B1 level, and the flexural bearing capacity of the sandwich panel is Lo/200 when the deflection of the sandwich panel is Lo/200 (Lo is the distance between the supports). Not less than 0.5Kn/m2. The effective width of the sheet is usually 1000mm, and the length can be customized.

The production of polyurethane sandwich panel requires an advanced continuous production line for sandwich panels. The process is cold-bending of inner and outer galvanized (aluminum-zinc) color steel plates, and the middle is coated with polyurethane rigid foam. The anti-seepage sandwich roof panel with patented technology maximizes the advantages of polyurethane sandwich panels.
