INTRODUCTION
Donpanel 422/PIR blend polyols is a compound which consists of polyether & polyester polyols, surfactants, catalysts and flame retardant in a special ratio. The foam has good thermal insulation property, light in weight, high compression strength and flame retardant and other advantages. It is widely used to produce continuous sandwich panels, corrugated panels etc, which applies to make cold stores, cabinets, portable shelters and so on.
