WHAT IS THE DIFFERENCE BETWEEN POLYURETHANE SANDWICH PANELS AND FOAM SANDWICH PANELS?
What they have in common is that both sandwich panels have a hard protective layer. The difference lies in the different substances in the medium.
The production of polyurethane sandwich panels requires continuous sandwich lines with improved ends. The process includes cold bending of internal and external galvanized (aluminum-zinc) color steel sheets, and in-line spraying of black and white polyurethane raw materials in the middle.
Polyurethane sandwich panel appearance is beautiful, bright and has a good comprehensive effect. It integrates load-bearing, heat insulation and waterproofing, and does not require secondary decoration.
It has a wide range of uses, especially for temporary surveying of construction sites such as offices, warehouses, fences, etc., and also reflects the rapid and civilized construction of modern engineering, especially in terms of rapid installation and use, which is of great significance.
The exponential reduction in the cost of temporary measures at construction sites has had a huge impact in terms of assembly and disassembly, as well as the rotation and reuse of materials, which are essential for new lightweight building materials.
Polyurethane wall panel can produce 50mm, 75mm, 100mm polyurethane wall panel, conventional appearance board has corrugated, flat or clean small surface, invisible nails, can be installed horizontally or vertically, color steel outer plate thickness 0.4mm-0.8mm, inner plate 0.4mm-0.5mm, insulation core material for polyurethane (PU), fire grade B1, B2, apparent density 40KG/cubic, effective width 1 meter, length can be processed according to requirements, environmental protection, energy saving, good thermal insulation effect, beautiful atmosphere.
