Description

PU sandwich panel usually be named as polyurethane sandwich panel(custom clean room rock wool panel), PU color steel panel aas well as PU composite panel, and it has three layers, which contains double color steel sheet and the PU core, thus, it havs good insulation feature and smoothness.
Polyurethane material is a polymer material. Polyurethane is an emerging organic polymer material and is known as the fifth largest plastic. It is widely used in many fields of the national economy due to its excellent performance. PU Sandwich Panel applications  cover the fields like light industry, chemical, electronics, textile, medical science, construction, building materials, automotive, defense, aerospace, aviation and so on.
PU Features
1. Hard polyurethane has low thermal conductivity but good thermal performance. When the density of rigid polyurethane is ****0 kg/m3, and the thermal conductivity is only 0.**8~0.**4w/(m.k), which is equivalent to half of EPS and the lowest thermal conductivity of all thermal insulation materials.
2. Rigid polyurethane has moisture and water resistance. The rigid polyurethane has a closed cell ratio over *0%, and it is a hydrophobic material. It does not increase the thermal conductivity due to moisture absorption and seep proof wall.
3. Rigid polyurethane fire, flame retardant and high temperature. Polyurethane is a flame-retardant self-extinguishing material after adding flame retardant. Its softening point can reach above **0℃. It will only decompose at higher temperature, in addition, polyurethane will be in its foam when burned. Carbon deposits form the surface, which helps to isolate the underlying foam. It can effectively prevent the spread of flame. Moreover, polyurethane does not generate harmful gases at high temperatures.
4. Due to the excellent thermal insulation performance of the polyurethane sheet , the thickness of the outer protective structure of the building can be reduced and the indoor use area can be increased.
