Efficient heat preservation Because the thermal conductivity of the foaming agent used in polyurethane is much lower than that of air (good heat preservation performance), the heat insulation performance of polyurethane rigid foam is better than those of materials that only contain air, such as mineral wool, glass fiber and polystyrene.
Moreover, its unique closed cell and high gas diffusion resistance make it have excellent long-term insulation performance, and its thermal insulation performance can last for 20-50 years or more;
The closed-cell structure of the excellent corrosion-resistant polyurethane rigid foam and the surface material used make it have better air and water resistance, and it can be made into an inlaid connection structure during molding, which is easy to post-assemble. It does not require an additional insulating layer to prevent moisture and saves a lot of trouble in laying an insulating layer. These properties are not available in other insulating materials at the same time;
Wide, light, and thin walls, because the rigid polyurethane foam acts as a structural material at the same time, the overall structure has the advantages of light weight, large span, and high load.
Compared with other insulating materials, polyurethane rigid foam has the best thermal insulation performance. Therefore, thinner polyurethane sandwich panels can meet the relevant regulations on building energy consumption limits, which allows the use of thinner panels during construction and saves building space; stable quality and high production efficiency. In the case of a sharp increase in demand, the factory production line of polyurethane sandwich panels not only facilitates quality control, but also brings good economy and competitiveness;
Good weather resistance and easy to install. After the polyurethane sandwich panel is prefabricated in the factory, it can be directly used for construction and installation without additional procedures, and the construction is fast. And no need to take into account the changes in the weather, the production is carried out as planned.
