PU sandwich panels:
Polyurethane Sandwich Panel also called PU Sandwich Panel,the top & bottom sheet of this panel is Galvanized & Pre-painted steel sheets,and core material is 5 components Polyurethane glue, it is formed by heating, foaming & laminating. Polyurethane is the best material for heat and sound insulation. It can reduce the heat transmission caused by difference in the internal and external temperature, and get to maximum efficiency of freezing and refrigeration systems. It is a new type of heat insulation material for lower construction cost.Panels are in multiple varieties and specifications to meet the need of various sites and projects.
