fiberglass PU Foam panels manufacturer in china
Manufacturers create fiberglass PU sandwich panels using glass-reinforced polymer and PU (polyurethane) foam, making them a popular insulating composite panel. They are very insulating, durable, and lightweight composite materials. It covers all the properties of FRP and PU foam.
Because of its many advantages, it is widely used in refrigerated trucks, cold rooms, partitions, house insulation, and other indoor and outdoor applications.
Features
Composite-box produces fiberglass PU sandwich panels with a maximum length of 12 meters and a maximum width of 3.6 m. They consist of two sides of a fiberglass sheet with a PU foam core in the middle. They bond the materials with high-quality PU glue, using vacuum and high-pressure bonding, which creates a very strong and crack-resistant result. Cut grooves in the PU foam sheet; the benefit is to prevent bulging and balance the force. They are frequently used in refrigerated trucks.
Special processing
We can provide a variety of processing methods, in addition to the conventional methods, offering matte, embossed, and other surface treatments. We can customize the panels in RAL color and different sizes, adding reinforcing materials such as reinforcing steel, wood, and aluminum profiles, so that you can use your panel in more specialized scenarios.
Finished product production.
As a high-quality FRP PU panel manufacturer in China, we can not only provide panels but also complete products; we can produce specialized refrigerated box truck bodies, refrigerated trailers, caravans, etc. We have been producing FRP PU panels for over 20 years. This is thanks to our 20 years of continuous product research and investment in R&D, which has resulted in more and more satisfied customers.

Structure of fiberglass PU
PU foam
PU foam is a synthetic plastic with a closed-cell structure that has very high thermal insulation properties. It is widely used in thermal insulation applications. The thermal conductivity is 0.18~0.25W/mk.
FRP fiberglass sheet
FRP is a high-performance material with good physical properties and consists of glass fiber reinforcement. It possesses high performance, high compression resistance, and UV resistance.
Application of fiberglass PU Sandwich panel
Commonly used for refrigeration, warming, freezer applications.
