There are clear performance requirements for cold storage panels. According to GB/T 23932-2009 "Metal-Faced Insulated Sandwich Panels for Buildings," the panel thickness must be ≥0.5mm, the core material density must meet design requirements (e.g., polyurethane density ≥40kg/m³), and it must pass a -18℃ low-temperature bending test without cracking. Simultaneously, the fire resistance rating of the panels must comply with GB 8624-2012 standard, with rock wool panels requiring Class A non-combustible properties and polyurethane panels requiring Class B1 flame retardant properties.
Polyurethane cold storage panels are building materials used in the construction of cold storage facilities, refrigerated warehouses, refrigerated trucks, and other cold chain facilities. They possess excellent thermal insulation performance and good structural stability, and are widely used in the food, pharmaceutical, and chemical industries.
