PU Sandwich Panels Manufacturers in Pakistan
Best PU Sandwich Panel Manufacturers in Pakistan
The face material of the polyurethane sandwich panel is made of a high-quality color-coated steel plate. The core material is made of high-quality rock wool, glass wool, and high-density rigid foamed polyurethane as the groove filling.
After high-pressure foaming and curing, the cotton is automatically compacted and compounded by super-long precision double crawler control molding.
Compared with traditional hanging cotton enclosure materials, it has better fireproof and thermal insulation effects, longer performance, and superior thermal insulation performance.
The thermal insulation effect of the same thickness is twice that of the EPS sandwich panel.
The polyurethane cold storage panel has a large span, fast drainage, good waterproof effect, hidden screws so that it is not easy to rust, which extends the service life of the panel.
Definition PU Sandwich Panle
The inner and outer sides of the PU sandwich panel are glass steel plates, and the rigid polyurethane foam of the sandwich layer is compounded by German vacuum technology and high pressure. The surface of the sandwich panel is smooth and clean, and dirt can be easily removed. The entire panel is brightly colored and has excellent gloss retention.
Advantages of PU Sandwich Panel
Because the thermal conductivity of the foaming agent used in the PU board is much lower than that of air (good insulation), the insulation performance of PU rigid foam is better than pure air materials such as mineral wool, glass fiber, and polystyrene. In addition, its unique closed-cell and high gas diffusion resistance make it have excellent long-term insulation performance, which can last 20-50 years or more.
The closed-cell structure of polyurethane rigid foam and the surface material used make it have excellent air resistance and moisture resistance and can be made into a mosaic structure during the molding process, easy to assemble. It does not require an additional insulating layer to protect it from moisture and thus does not require many insulating layers. Other insulating materials cannot achieve these characteristics.
3.Wide, light, and thin-walled.
Since PU rigid foam is used as a structural material at the same time, the overall structure has the advantages of a lightweight, large span, and high load. Compared with other insulating materials, polyurethane rigid foam has insulating properties. Therefore, thinner polyurethane sandwich panels can meet building energy requirements and allow thinner panels to be used during construction, saving building space.
4.Stable quality and high production efficiency.
Nowadays, in the case of a sharp increase in demand, in addition to the convenience of quality control, the production line of the factory producing polyurethane sandwich panels has also brought a good economy and competitiveness.
5.Good weather resistance and easy installation.
PU sandwich panels are prefabricated at the factory and can be used directly for building installation without additional processes and structures. And there is no need to consider whether changes to planning production.
The product is a synthetic material with excellent properties. It has the advantages of high specific strength and low thermal conductivity. It is mainly used as an insulating material, followed by structural materials.
Application of PU Sandwich Panel:
PU Sandwich Panels are widely applied in insulation/refrigeration / dry truck compartments, large-span structural roofs, walls, thermal insulation (or fire protection) workshops, purification workshops, high- and mid-range combination houses, cold storage, container houses, etc.
