Polyurethane Sandwich Panel Wall Panels
Waterproof: Prevent rainwater from penetrating and protect the interior of the building.
Thermal insulation: Insulates heat, reduces heat transfer, and keeps the indoor temperature stable.
Energy saving: Reduces energy consumption for indoor air conditioning and heating.
Aesthetics: Provides a variety of colors and styles to enhance the appearance of the building.
Product Introduction
Polyurethane sandwich panels are a type of high-performance composite panels. Their core advantage lies in their excellent thermal insulation performance, thanks to the low thermal conductivity of polyurethane foam. They are also lightweight, high-strength, fire-retardant, waterproof, moisture-proof, and sound-proof. This type of panel is widely used in building walls, roofs, cold storage, transportation carriages, and home appliances. It is not only easy to install, but also can effectively improve energy conservation and environmental protection. With the growth of green building and energy-saving demands, polyurethane sandwich panels have a broad application prospect in modern industry and construction, becoming an indispensable and efficient material.

Flow Chart of Polyurethane
This diagram illustrates the polyurethane production process. It begins with unwinding, film covering, and pressing for shaping. Next, spraying, preheating, and foaming give the material its polyurethane properties. The material is then guided, cut to size, cooled for stabilization, and finally unloaded and packaged.
Our Factory
The various production lines within the factory work closely together, the distance between parts and components from one workshop to another is short, and the material flow is fast, which reduces the logistics cost of the production process and avoids additional costs caused by multiple loading and unloading.
Service
We provide support throughout the entire purchasing process. We offer on-site installation and consultation, extended warranties and replacement services to ensure a seamless and worry-free experience.
