Product Details
PU foam sandwich panel, also known as polyurethane sandwich panel and polyurethane composite panel, is a high-performance building panel. PU sandwich panel consists of two layers of metal plates (such as glass steel plate or color steel plate) inside and outside and a rigid polyurethane foam sandwich layer in the middle. These materials are tightly bonded together through advanced vacuum technology or high-pressure composite processes to form a cohesive structure.
Features of PU foam sandwich panel
1. Thermal insulation: rigid polyurethane foam has extremely low thermal conductivity, so PU foam sandwich panel has excellent thermal insulation performance.
2. Fire and moisture prevention: The surface material and insulation material of sandwich panels are non combustible and have been treated with special coatings to improve their fire resistance. At the same time, polyurethane foam itself also has certain moisture resistance.
3. Light weight and high strength: PU foam sandwich panel is light in weight, but has high strength and stiffness, and can withstand certain loads.
4. Beautiful and durable: the sandwich panel has high surface finish, bright colors, excellent light retention, and is not easy to change color, corrosion resistant, sun proof, and anti-aging.
5. Easy installation: Sandwich panels can be customized according to user needs, and installation is simple and fast, without the need for complex construction steps.
