PU Sandwich Panel

PU Sandwich Panel PU Sandwich Panel PU Sandwich Panel

1. Protective Film
2. Color Steel Plate
3. High Strength Adhesive Layer
4. Non-combustible Sandwich Layer Materials(PU)
5. Color Steel Plate

Our PU sandwich panel not only has the various features of EPS sandwich panel, but also comes with difficult combustion properties and a wide range of operating temperature from -196 ℃ ~ + 130 ℃. What's more, this product offers many merits of small shrinkage ratio, no sign of embrittlement, non-toxic and no corrosion as well as low, stable, thermal conductivity. It is a heat insulating material, ideal for cold storage projects. Also, this product is widely used as the roof, wall of steel structure workshops, movable houses and integration house or as the partition wall, suspended ceiling of clean rooms.

The PU sandwich panel is mainly composed of protective film, color steel plate, high strength adhesive layer, and non-combustible sandwich layer. The non-combustible sandwich layer is obtained from PU which has low thermal conductivity and good thermal insulation property. With 6.5 ng/Pa.m.s of water vapor permeability coefficient and 3 % or 4 % water-intake rate, our product is quite convenient to install.

SBS is a professional PU sandwich panel manufacturer in China. We offer a broad range of products, including floor decking steel sheet, gable frame steel structure building, modified container house, and more.

  • Rockwool Sandwich PanelRockwool sandwich panel offers up to 600 ℃ operating temperature and grade A non-flammability, therefore greatly expanding its range of application and being a light-duty panel suitable for those buildings which has a high demand on fire resistance rating. However, compared with EPS and PU sandwich plate, this product is not so outstanding in some aspects including dead weight, heat conduction, compressive strength, and water-intake rate.
  • EPS Sandwich PanelEPS sandwich panel takes color steel plate as surface layer, flame retardant polystyrene foam board as the core material, two component polyurethane as adhesives. It is manufactured by continuous heating and pressing, composite molding, and then cutting to length. Foam board integrates two layers of color steel plate by adhesives, and its compressive strength is about 100KPa.
