Product Description
What's Polyurethane sandwich panels?
Polyurethane Sandwich Panel also called PU Sandwich Panel,the top & bottom surface of this panel is Galvanized & Pre-painted steel sheets, 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. After tested bynational authoritative testing organization, all technical indicators comply with national standards.
It is suitable for the various roofs and walls referring to the large-size factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purifications workshops, etc, which features temp-keeping, heat insulation, weight-bearing, weatherproof with the rich colorfulness and good appearance.
Sandwich panel is a structure made of three layers: low density core inserted in between two relatively thin skin layers. This sandwich setup allows to achieve excellent mechanical performance at minimal weight. The very high rigidity of a sandwich panel is achieved thanks to interaction of its components under flexural load applied to the panel: core takes the shear loads and creates a distance between the skins which take the in-plane stresses, one skin in tension, the other in compression. General information on sandwich panel structure, different sandwich core types available and the potential with respect to weight savings is available in the following reference.
Applications
Sandwich panels are used in those applications where high structural rigidity and low weight is required. An evident example of use of sandwich panels is aircraft where mechanical performance and weight saving is essential. Other applications include packaging (e.g. fluted polypropylene boards of polypropylene honeycomb boards), transportation and automotive as well as building & construction.
