Item Name: PU-core sandwich panel Model No: CX-PU
Structure --Polyurethane sandwich panels are made by upper and lower layers prepaint galvanized steel sheets, to the middle infused polyurethane foam, through heating, pressure, and the formation of foam sandwich panels.The metal top layer can be a colored stencil plate , Polyurethane core sandwich panel is universally acknowledged the best material of heat insulation and heat preservation nowadays. it can perform a good anticorrosion, antirust and anti-weathering
Features:
(1)High load-bearing ability and good integral stiffness
Because the PU-core sandwich panel is shaped by solidification and pressurization after injecting two layers of stencil plates into liquid state and the polyurethane oneself is colloidal, PU panel has extremely good integrity. In addition the hydraulic pressure type that the above surface of roof boarding arises. Its whole steel degree is better than other similar materials far. Adopting the roof boarding of PU can save purlin and use the steel for 1/3--2/3.
(2) Excellent waterproof and airtight performance
It is rational and simple and convenient to join: The roof panel adopts the way of fastening, which avoided the hidden danger that leaks in the roofing. The wall panel adopts the common tongue and groove connection, whose appearance is beautiful and save the consumption of the accessories.PU hard foam could stick well to the steel sheet, cement, fiber panel, brick etc. They will rid off easily thus enhance the heat reserve and waterproof effect. Hidden screws system meets the aesthetic requirements of the construction,The construction is simple and convenient.
(3)The unique froth technology: There are symmetrical holes on the panel, the thermal conductivity is low, the dimension is stable, suitable for the low pressure and high pressure construction.
(4)Support is good, heat insulate, sound insulate, sound absorb, light weight, non-toxic, no special smell and enviroment protect.
(5) Quick and easy installation
PU sandwich panel needn’t be produced at the scene.It does not only maintain the surroundings clean & tidy and do not affect the other proess normally, but also shorten the installation cycle. PU sandwich panel can be installed 600 ~ 800 m2 per day.
(6)Aesthetic feeling
The exterior of the sections can have mortar or coating applied directly on site, or in the factory, or can be sheeted directly with siding or cladding as the project requires. They can also have stucco, wall covering, tiles, marble or other different finish styles to meet your aesthetic needs.
