Rigid PU Foam Insulation for Sandwich Panel (Discontinuous Processing)
We have developed the rigid polyurethane foam system for CFC free blown rigid polyurethane sandwich panel. Aside from isocyanate, it also includes system polyol which is mixed with polyol, fire retardant, silicone surfactant, catalyst, and additives. Our rigid PU foam insulation for sandwich panel is made with the discontinuous processing method. It is used to make sandwich panel by filling with dispensing machine or manual pouring in mould.
There are two kinds of foaming systems such as HCFC-141B or all-water-blown based types.
Performance
This rigid PU foam system is good in flowabiltiy, short in stripping time. It is convenient to use. The rigid PU foam comes with uniformly distributed cells, good dimensional stability, and excellent thermal insulation property. It has good viscosity on many substrates. In conclusion, its performance reaches the international advanced level.
