Austrian aluminum plate heat preservation refrigerated truck

Intermediate insulation layer rigid polyurethane foam

The insulation layer uses cyclopentane polyurethane as a whole to be injected and foamed at one time, no seams, no gaps, good heat insulation and high strength

Non-toxic gas release, environmental protection

Low thermal conductivity

Low thermal conductivity of polyurethane K = 0.023w / k.m2. Higher than XPS board (K = 0.028 ~ 0.035w / k.m2)

EPS foam board

(K = 0.024W / m.K ~ 0.041W / m.K

Density:

The density of PU polyurethane board is as high as 42-45kg / m3,

Density of XPS extruded polystyrene ≤38kg / m3

 EPS polystyrene particle foam density reaches 15-30kg / m3
