The Main Components Of Polyurethane Sandwich Panels

The main components of polyurethane sandwich panels include outer sheet, polyurethane foam layer and inner sheet. The outer sheet is usually made of galvanized sheet, color steel sheet or stainless steel sheet, which is used to protect the internal materials of the sandwich panel and increase the weather resistance and aesthetics of the sandwich panel. The polyurethane foam layer is the core part of the sandwich panel, which has good thermal insulation performance and structural stability, can effectively reduce heat conduction and improve the thermal insulation effect of the building. The inner sheet is usually the same as the outer sheet, which is used to fix the polyurethane foam layer and enhance the structural strength and stability of the sandwich panel.

The characteristics of polyurethane sandwich panels include:

Excellent thermal insulation performance: polyurethane foam has a low thermal conductivity, which can effectively reduce heat conduction, improve the thermal insulation effect of the building, and reduce energy consumption.

Lightweight: polyurethane foam has the characteristics of lightweight, which can reduce the weight of the building itself, reduce the load of the building, and reduce the use of building materials.

Easy to process: polyurethane sandwich panels have good plasticity and processability, and can be cut, bent and processed according to the needs of the building, which is convenient for construction and installation.
‌Strong weather resistance‌: The outer layer of the board has been specially treated to have good weather resistance, can resist wind, rain and ultraviolet radiation, and maintain the long-term beauty of the building appearance‌.
Polyurethane sandwich panels are widely used for insulation and heat insulation of building exterior walls, roofs, floors and other parts, especially for industrial plants, warehouses, cold storage and other places that require large-area insulation. Its excellent thermal insulation performance, lightweight characteristics and easy processing make it an ideal choice in the field of building insulation‌.
