High-quality Closed-cell Structure Core Material
Polyurethane rigid foam is a new closed-cell structure synthetic material with thermal insulation and waterproof functions. Its thermal conductivity is only 0.022-0.033W/(m*Κ), which is equivalent to half of the extruded board and has the lowest thermal conductivity among all thermal insulation materials.
Multiple Specification Options
TOPOLO PU foam composite panel has a variety of specifications to choose from. The PU core material can be composited with various skin materials such as fiberglass sheets, aluminum sheets, and steel sheets. Different combinations can be selected depending on the use of the final product.



Why Choose Fiberglass PU Sandwich Panels?
FRP skin PU sandwich panels are undoubtedly one of the best composite structures. It combines thermal insulation, sound insulation, light weight, robustness and water resistance. At the same time, its cost is lower than that of aluminum panels.
Fiberglass Composite Materials are The Trend of Lightweight Development
The skin of the PU sandwich panel is made of FRP or CFRT (continuous glass fiber reinforced thermoplastic) material, and the surface of TOPOLO FRP material uses a yacht-grade gelcoat layer, which is smooth and durable. The color and texture of the FRP surface can be customized.

Strengthen the Structure
For heavier pressures, reinforcing structures can be embedded inside the PU sandwich panels, embedded structural materials are aluminum tubes, steel tubes, and plastic brackets.
Application Field of PU Foam Sandwich Panels

PU foam panels are widely used in refrigeration equipment, such as cold rooms, mobile rooms, refrigerated trucks, and so on. It will not brittle at ultra-low temperatures above 40 degrees, at the same time, it saves about 10% of energy during transportation.

The lightweight and strong properties of Fiberglass PU foam panels make it widely used in caravans, motorhomes, campers, and travel trailers.

PU sandwich panels can be used for interior walls, exterior walls, and roofs of buildings, and they will have good fire performance by adjusting the formula. In particular, it is compounded with metal panels to enhance its flame-retardant properties.
Choose TOPOLO PU Foam Sandwich Panels
TOPOLO New Material is a professional manufacturer of thermoplastic sandwich panels in China. Besides the PU core, we also supply various panels with different cores, such as PP, PET, balsa wood, etc.
