Polyurethane sandwich panel

Description of Product: 

In terms of material proportioning and technical output of Zhongjie PU product, six-component mixed pouring technology (SIMENS) allowing on-line automatic operation which is art-of-the-date is adopted to take the lead in achieving six-component continuous foaming in China and finish proportioning process on line at one time. Besides, the formula can be adjusted in accordance with the environmental change to match with air-entrapping mixing unit to bring more well-distributed materials and finer foams for the purpose of producing high strength, energy saving, and environment friendly building panels

Polyurethane Sandwich Panel advantages

1. Effective insulation

The thermal conductivity coefficient of the rigid polyurethane(PU) foam can be 0.018-0.024 w/(m*k), which is only the half of expanded polystyrene(EPS), if its density is 38-42kg/m³. Rigid polyurethane foam is the best organic insulating material.

Since the thermal conductivity coefficient of the vesicant used is much lower than air, the insulating property of rigid polyurethane foam is better than rock wool, glass wool, expanded polystyrene and extruded polystyrene. Moreover, its insulating property can be sustainable for more than 30 years for its special closed-cell structure and resistance to gas diffusion.

2. Excellent corrosion and weather resistance

The polyurethane foam performs well in corrosion and weather resistance for its closed-cell structure and its surface material.

3. Moisture proof and waterproof

4. Anti freeze-thaw and sound absorption

The rigid polyurethane foam also performs well in anti freeze-thaw and sound absorption.

5. Energy efficiency and cost saving

Although the price is much higher than other alternatives, taking into account the excellent insulating property of the polyurethane foam, the increased costs will be offset by a substantial reduction in heating and cooling costs. Furthermore, we can reduce the thickness of external structure of the building by using thinner polyurethane foam to achieve the same insulating requirements, thereby increasing the indoor area.

6. Fireproof and high temperature resistance

Rigid polyurethane foam is a flame-retardant and self-extinguishing material after. It can reach a softening point of 250 degrees Celsius and decomposes at a higher temperature. A layer of carbon will be formed if it is lighted, which will effectively prevent the spread of the flame.

7. Anti-deformation and hardly to be cracked

The average life expectancy of rigid polyurethane foam can be more than 30 years under normal use and maintenance. It won’t be destroyed by fungi and algae growth, or rodents.

8. Beautiful appearance and easy installation

The polyurethane foam can be bonded with different surface materials, such as color steel plates, cement fiberglass cloth, aluminum, stainless steel and so on. So there are a lot of beautiful appearances and structures for customers’ choice according to their different specific requirements. It can be easily installed with fasteners because it is prefabricated in factory, which will significantly reduce the cost and shorten the schedule of construction.

Applications

PU Sandwich panels cover all applications in steel building construction and prefabricated houses: external walls, roofs, partitions, ceiling panels, acoustic sandwich panels for workshops,warehouse,cold room, industrial factory buildings, office buildings, stadiums, villas, and public buildings, etc.
