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 Pptions

TOPOLO PU foam composite board has a variety of specifications to choose from. The PU core material can be composited with various skin materials such as fiberglass sheet, aluminum sheet and steel sheet. Different combinations can be selected depending on the use of the final product.

Why Choose Fiberglass PU Sandwich Panels?

Fiberglass PU composite panel is undoubtedly one of the best composite structures. It combines thermal insulation, sound insulation, light weight, firmness, and waterproofing properties. At the same time, its cost is lower than that of aluminum panels.

The panel skin is laminated in different directions, keeping the fiber continuity, and reinforces the material in every force direction. This part is lightweight and strong in specific strength and specific modulus. It is water, corrosion, impact, and rubber resistant, and inert to most acids and alkalis. The skin is also recyclable with no gas pollution.

Application Field

Refrigerated truck body
Application in refrigerations

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.

Application in RVs

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

Application in Buildings

PU sandwich panels can be used for interior walls, exterior walls and roofs of buildings, and it will have good fire performance by adjusting the formula. In particular, it is compounded with metal panels to enhance its flame retardant properties.

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.
