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
