A brief introduction:

The metal-faced rigid polyurethane sandwich panel (hook panel) produced by Changzhou Yanghu Refrigeration is made of double-sided 0.4mm color steel, with flame-retardant insulation board (with a protective film), and has good thermal insulation performance.

The hook plate is made by hand, the metal panel is formed into the mold, and the inner is formed by the injection of polyurethane (PU) sandwich material, which has good insulation and heat insulation.

The traditional eccentric hook pin is used, and the connection is locked with a hex key. Each board hook is connected, whether it is used as a wall board or a ceiling board, it has good strength.

The main advantage:

1. Rigid polyurethane has low thermal conductivity and good thermal performance.When the density of rigid polyurethane is 35~40kg/m3, the thermal conductivity is only 0.018~0.024w/(m.K), which is equivalent to about half of EPS, which is the lowest thermal conductivity among all thermal insulation materials at present.

 2. Rigid polyurethane has moisture-proof and waterproof properties.The closed cell rate of rigid polyurethane is above 90%, which is a hydrophobic material, which will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water.

 3. Rigid polyurethane fireproof, flame retardant, high temperature resistance.After adding flame retardant, polyurethane is a flame-retardant self-extinguishing material, its softening point can reach more than 250 degrees Celsius, and only decomposes at higher temperatures: in addition, polyurethane will burn in its foam when burning. Carbon deposits form on the surface, and this layer of carbon helps insulate the underlying foam. Can effectively prevent the spread of flames. Moreover, polyurethane does not generate harmful gases at high temperatures.

 4. Because the polyurethane sheet has excellent thermal insulation properties，

Under the same thermal insulation requirements, the thickness of the outer envelope of the building can be reduced, thereby increasing the indoor area.

5. Strong anti-deformation ability, not easy to crack, stable and safe finish.

 6. Polyurethane material has stable porosity structure and strong airtight performance. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption.The average lifespan of the rigid foam polyurethane insulation structure can reach more than 30 years under the condition of non-human destruction. It can be achieved under normal conditions of use during the life of the structure, dry, wet or galvanic corrosion, as well as due to insect, fungal or algal growth or due to rodent damage and other external factors will not be damaged.

7. Scientific design, simple and practical, new thermal insulation material that saves construction costs

8. Metal panels of different materials and thicknesses can be customized according to actual needs.

Comprehensive cost-effective. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by a substantial reduction in heating and cooling costs. At present, Yanghu Company can produce sandwich panels of different sizes from 5cm to 20cm. Tel: 0519-88781801 Fax 0519-88787377.
