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.
