1.Product Introduce
Polyurethane Sandwich Panel also called PU Sandwich Panel, the up & down surface of this panel is Galvanized & Pre-painted steel sheets, core material is 5 components Polyurethane glue, it is formed by heating, foaming & laminating. Polyurethane is the best material for temperature keeping and sound insulation. It is widely used as the wall or roof for cold storage, industrial workshop, public building etc.

Advantages
(1) Its thermal conductivity item is 0.015~0.025W/(m·k) due to polyurethane high bond strength, no need to any anchors and bonder, it is a nature bond materials, it can make continue heating preservation layers.
(2) endurance good and polyurethane porosity structure stable, generally is closed hole, so not only well temperature keeping but also anti-freeze, sound insulation.
(3) High anti bending strength, Hard foam polyurethane is high strength material(material strength and volume rate) as preserve heating material which function is better than foam polystyrene
(4) Not absorbent water and well watertight of foam polyurethane with good water proof, gas barrier property, material not including water, low water absorbent
(5) Anticorrosive.
(6) Anti insects and rat-bite.
(7) polyurethane with good flame retardant is a hard to burn materials when adding flame retardants
(8) Polyurethane with big temperature durance is a soft and big deform material.
(9) Polyurethane with good environment protection which often is used in outside wall heating preservation

FAQ
ZJT brand color plate: 0.5mm, 0.6mm, 0.8mm. The Bao-steel brand is the best in China. Other supplier may use 0.326mm, and 0.426mm, not Bao-steel brand, which are too weak.
No. The best density is 42kg/m3. We can do the 42kg/m3 to ensure the best insulation.
Flame retardant is bad materials. It will cause the dense smoke and poor insulation.
The cold room market is so competitive in Alibaba. Some supplier focus on the price, and some focus on the quality. We only do the high quality cold room. All our panels are designed based on 20 years life time ZJT brand color plate and high density-42kg/m3.
We can grantee you 3 years warranty and design the PU panels used for 20 years. Compared with suppliers, some give 1 year warranty, some even no warranty grantee.
50/ 75 /100 /120/150/180/200 mm
The length of PU panel can be customized. The standard width is 960 mm
EPS and PU panel all have thermal insulation function, but EPS insulation ability is not good, without zinc-cam lock, easy to break out. In general, most cold room use PU panel now.
