HUAYU PU Sandwich panel for factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purifications workshops

HUAYU PU Sandwich panel (Polyurethane sandwich panel) is composed of 2 layers of color steel sheets and jetted the hard forms of polyurethane between 2 layers which feature fireproof materials. It is suitable for the various roofs and walls referring to the large-size factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purifications workshops, etc, which feature temp-keeping, heat insulation, weight-bearing.

In terms of raw material proportioning and process output, HUAYU products employ the globally advanced six-component online automatic operation mixing and pouring technology and have realized six-component continuous foaming for the first time in China. With the technology, mixing and proportioning process may be finished in an online way in a single time; The formula may be adjusted according to environmental changes; Air feeding and mixing devices may be used to make raw material mixing more even and foam finer, thus producing high-strength, energy-saving and environment friendly building boards. 

Core Advantages of HUAYU polyurethane Panels

1.      Energy-saving and heat-insulation: The closed cell rate is equal to or larger than 97% and heat insulation performance is excellent.

2.      Fire-resisting performance: The products have passed the inspection by National Center for Quality Supervision and Test of Fixed Fire-extinguishing Systems and Fire-resisting Building Components and proved to be in line with the requirement of grade in GB8624-2006

3.      Air Tightness and sound insolution: The products have great sound insulation and decrease the sounds due to impacts of rainwater or hailstone. environmental noise prevention, composite board insulation strength up to 40-50 dB, is very effective sound insulation material

4.      Environmental Friendly: Being free from formaldehyde and microorganisms, it may be recycled

5.      Actistical appearance and high economical efficiency: The products have diversifying surface forms and colors. Besides, they consume less materials and therefore save both construction time and construction cost

6.      Quick and Easy Construction: Polyurethane panels are produced in the highly controlled environment with constant temperature and therefore have steady quality. They may be constructed quickly. They have been applied for over 35 years.
