What are the differences between polyurethane sandwich panel and foam sandwich panel？

The production of polyurethane sandwich panels requires a continuous sandwich panel production line with improved ends. The process includes cold bending of internal and external galvanized (aluminum zinc) colored steel plates, and online spraying of black and white polyurethane raw materials between them.

Polyurethane sandwich panels have a beautiful appearance, shiny appearance, and good overall effect. It integrates load-bearing, thermal insulation, and waterproof functions, and does not require secondary decoration.

It has a wide range of uses, especially for temporary measurements on construction sites such as offices, warehouses, fences, etc. This also reflects the fast and civilized construction of modern engineering, especially in terms of rapid installation and use, and is of great significance.

The significant impact index in assembly and disassembly, as well as material rotation and reuse, significantly reduces the cost of temporary measures on construction sites and will be an essential new type of lightweight building material.

Polyurethane wall panels can be produced in sizes of 50mm, 75mm, and 100mm. Conventional exterior panels have corrugated, flat, or clean surfaces, invisible nails, and can be installed horizontally or vertically. The thickness of the color steel outer panel is 0.4mm-0.8mm, and the thickness of the inner panel is 0.4mm to 0.5mm. The insulation core material is polyurethane (PU), with fire ratings of B1 and B2, an apparent density of 40KG/cubic meter, an effective width of 1 meter, and a length that can be processed according to requirements. It is environmentally friendly, energy-saving, has good insulation effect, and has a beautiful atmosphere.
