fiberglass PU Foam panels manufacturer in china

Fiberglass PU sandwich panels are popular high-strength insulated composite panels. Manufactured using fiberglass/GRP and polyurethane foam, this composite material offers excellent thermal insulation, durability, and lightweight properties, combining all the advantages of both fiberglass-reinforced polymer (FRP) and polyurethane foam.
Due to its numerous advantages, it is widely used in refrigerated truck bodies and RV bodies, as well as cold storage facilities, partitions, home insulation, and other indoor and outdoor applications.

Outstanding thermal insulation performance
Not easy to corrode; impact resistance.
CNC is easy to process and easy to install.

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.

Refrigerated box truck body
Refrigerated trailer
Building insulation
Cold storage
