High cutting precision, thickness error of ±0.5mm, so as to ensure the surface flatness of the finished products.
fine foam, even bubble hole.
Light bulk density can reduce the self-weight of finished products, 30-60% lower than traditional products.
Large compressive strength, can withstand the production of finished products in the process of great pressure.
Convenient quality inspection, because in the cutting process to remove the surrounding skin, the quality of the plate at a glance, to ensure the thermal insulation effect of the finished products.Thickness can be produced and processed according to user's requirements.
Advantage of PU Sandwich Panel
1. Because the heat conductivity of the foaming agent used by polyurethane is much lower than that of air (good insulation performance), the thermal insulation performance of polyurethane rigid foam is better than that of air-only materials such as mineral wool, glass fiber and polystyrene.Moreover, its characteristic obturation and high resistance to gas diffusion give it superior long-term insulation performance, which can last 20-50 years or more.
2: excellent corrosion resistant polyurethane rigid foam with closed-cell structure and surface material, so that it has better air and water resistance performance, and it can be made into a Mosaic connection structure when forming, easy to assemble after.It does not need the additional insulation layer moistureproof, saves a lot of laying insulation layer trouble.These properties are not available to other insulation materials at the same time.
3: wide, light and thin walls. As the rigid polyurethane foam ACTS as the structural material at the same time, the overall structure has the advantages of light weight, large span and high load.Compared with other insulation materials, polyurethane rigid foam has the best thermal insulation performance.As a result, thinner polyurethane sandwich panels can meet the building energy limits, which allow for the use of thinner panels during construction and save building space.
4: stable quality, high production efficiency nowadays, in the case of sharply rising demand, the factory production line production of polyurethane sandwich board, in addition to the convenience of quality control, but also it brings good economy and competitiveness.
5: good weather resistance, easy to install polyurethane sandwich board in the factory prefabricated, can be directly used for construction and installation, no additional procedures, construction fast.And regardless of the weather changes, planned production.
