(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

1. what is the thickness of the color plate?

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. 

2. For PU panels, the higher density the better insulation, right?

No. The best density is 42kg/m3. We can do the 42kg/m3 to ensure the best insulation.

3. If PU panel add flame retardant, what will cause?

Flame retardant is bad materials. It will cause the dense smoke and poor insulation. 

4. Why the price difference is so big in Alibaba?

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. 

5. What is the warranty for the PU panels?

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. 

6. What is thickness of PU panel?

50/ 75 /100 /120/150/180/200 mm

7. Can the PU size be customized?

The length of PU panel can be customized. The standard width is 960 mm

8. What is the difference between EPS panel and PU panel?

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.
