Product Details
PUR sandwich panel refers to the formulation system of polyether polyol, low isocyanate index (about 110~120) and flame retardant commonly used as the core material of polyurethane rigid foam. The skeleton structure of foam is composed of carbamate segments.
PUR is a polymer with repeated structural units of carbamate chain segments, which is made by the reaction of isocyanate and polyol. It has excellent material properties, wide applications, and a wide variety of products, of which PUR foam is the most widely used. PUR products are divided into foam products and non foam products. Foam products include soft, hard and semi hard PUR foam plastics. Non foaming products include coatings, adhesives, synthetic leather, elastomers, and elastic fibers.
PUR sandwich panel is an efficient and energy-saving building enclosure material, mainly composed of polyurethane rigid foam as the insulation layer, and composite with color steel plate or other metal panels. This type of board not only has excellent insulation performance, but also has good load-bearing, fireproof, waterproof and other functions, making it an ideal choice for industrial, logistics and warehousing, integrated housing and other construction fields.
PUR sandwich panels have a wide range of applications, mainly used for:
- Industrial plant: as a maintenance system for roofs and walls.
- Logistics warehousing: providing efficient insulation and thermal insulation solutions.
- Integrated house: a roof and wall maintenance system used for integrated houses.
- Other construction fields: such as cleanrooms, cold storage, commercial pavilions, etc.
