PU sandwich panels consist of two outer metal colored sheets with insulation polyurethane core between them. The metal sheets are bonded to the insulation core with specialized adhesives. The  surface of the panel can be flat, slightly corrugated, water ripple or with a significant profile (it can meet customer different demands). A huge assortment of shapes, coatings and colors is available. Our polyurethane sandwich panel installation requires only a limited number of mechanical fasteners (eg. screws), the resulting constructions avoid significant thermal bridging. To achieve distinctive architectural features, panels are connected with blind dowels.

Our PU sandwich panel has two automatic operations which is the most advanced in the globe and adopted to take the lead in achieving six-component continuous foaming in China and finish proportioning process on line at a time; On the other hand, the formula can be adjusted in accordance with the environmental change to match with air-entrapping mixing unit to bring more well-distributed materials and finer foams for the purpose of producing high-strength, energy-saving and environment-friendly building boards.

Specification:

I. What is Polyurethane Sandwich Panel :
  
Polyurethane sandwich panel choose high quality two layer color coated steel sheet or other precision forming metal surface material; After rolling forming, it will inject flame retardant polyurethane bubble liquid in the middle space, through high pressure foaming and curing process, with strong adhesion with metal surface to compound and become beautiful, smooth, tough building panel.  

II. Application of Polyurethane Sandwich Panel:
Polyurethane sandwich panel has been used as the main steel building palisade materials, widely used in large industrial plants, cold storage, garage, mobile homes, exhibition hall, gymnasium, shopping centers, airports, power plants, villas, hospitals, office buildings and other fields, and its excellent insulation performance is mainly used in roof and wall of industrial and civil construction.

III. Product Features of Polyurethane Sandwich Panel
