Decorative PU Sandwich Panel

The production process of decorative PU sandwich panel includes the cast polyurethane elastomer (CPUR) process, which is suitable for the production of large complex components. The chemical structure is diversified, the viscosity is easy to adjust, the processing technology is excellent, suitable for industrial production.

The use of decorative PU sandwich panels on the walls and roofs of public buildings such as schools, hospitals and office buildings can effectively reduce the energy consumption of buildings and contribute to the energy saving and emission reduction of society.

1. Wide hardness range. It still has the elongation and resilience of rubber under high hardness. The hardness range is Shore A10-D80.

2, High strength. Their tear strength, tear strength and load bearing capacity are much higher than that of general purpose rubber under rubber hardness. At high hardness, its impact strength and bending strength are much higher than plastic.

3, Wear. Its wear resistance is very outstanding, generally in the range of 0.01-0.10(cm3)/1.61km, about 3-5 times that of rubber.

4. Oil resistance. Sandwich wall panel is a strong polar polymer compound, and non-polar mineral oil has a small affinity, in the fuel oil and mechanical oil is almost not corroded.

5, Good oxygen resistance and ozone performance.

6, Good vibration absorption performance, can do vibration reduction, buffer effect. In the mold manufacturing industry, replace rubber and spring. Polyurethane material has good thermal insulation, sound insulation, noise reduction, buffer and seismic effects, and the construction cost is low.
