Our company offers professional polyurethane PU and EPS foaming sandwich panel production line. The sandwich panel is composed of two-layer forming metal panel (or panel made of other materials) and high polymer heat insulation inner core, which is made by direct foaming between panels and then maturation forming. In this way, this kind of panel is easy for installation, and it enjoys light weight and high efficiency. Besides, the filling system also adopts closing bubble molecular structure, thus condensation of water vapor is avoided.
