1.Products Introduction of PU sandwich panel
PU sandwich panel can be customized, including the thickness and color of double-side color steel sheet, the thickness and size of sandwich panel and more. If you want to replace the sandwich material with others, you can choose glass wool sandwich panel, rock wool sandwich panel, EPS sandwich panel and more.
The performarence of PU sandwich panel are mainly:
1. PU low thermal conductivity and good thermal insulation performance. It is equivalent to about half of EPS and has the lowest thermal conductivity of all thermal insulation materials.PU sandwich panel can play an important role in extreme weather, such as severe cold and high temperature.
2. It has moisture-proof and waterproof performance. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water.
3. It has the functions of fire prevention, flame retardant and high temperature resistance. After adding flame retardant, PU is a flame-retardant self-extinguishing material, and it will not produce harmful gases under high temperature conditions.
4. Strong anti-deformation ability, not easy to crack, stable and safe.
5. Good noise reduction performance.
6. Long service life, more than 30 years under normal use and maintenance conditions.

3.Product Feature And Application of PU sandwich panel
PU sandwich panel is more and more used in container house. It is the first choice for houses and container warehouses built in cold and high temperature areas. Container house has been popular in Canada, the United States, Europe and Northeast Asia for many years.
1. Excellent fire performance. According to the raw materials used in production, production technology and formula, the test results show that its fire resistance can exceed 1000°.
2. Good thermal insulation performance. According to the thickness of core material is different, thermal conductivity coefficient is lower, heat insulation effect is better.
3. Significant sound absorption and noise reduction. Polyurethane has a high sound absorption level and can absorb a wide range of frequencies.
4. The way of buckle and assemble is reasonable. Adopt embedded buckle connection, avoid the hidden trouble of house seam board leaking, reduce the cost of accessories.
5. Strong and durable, strong overall stiffness. Through the connection with purlins, the overall stiffness of the roof is greatly increased and the working performance is increased.
6. Flexible assembly, short installation cycle. Site without secondary processing,simple installation, shorten the overall construction period, save installation labor costs.
7. Convenient disassembly, repeated use, energy saving and environmental protection.
