- Product Description
-
Polyurethane (PU) sandwich panels are a common building material. "Polyurethane" is abbreviated as "PU" and is a polymer made from the reaction of isocyanate and polyol, featuring repeating units of urethane segments.
These sandwich panels use polyurethane foam as the core material. Both sides typically use metal panels such as color-coated steel sheets, aluminum sheets, or stainless steel sheets, which are combined with the core material through a specific production process. They have good thermal insulation properties, with a low thermal conductivity, effectively reducing heat transfer in buildings and lowering energy consumption; they also have excellent fire-resistant properties, with some products achieving certain fire-resistance ratings; in addition, they have high strength, light weight, and are easy to install, shortening construction time. They are widely used in the roofs and walls of buildings such as industrial plants, warehouses, cold storage facilities, and clean rooms.
