Donpanel 422 HCFC-141b base blend polyols for continuous PUR
INTRODUCTION
DonPanel 422/ PUR blend polyols is a compound which consists of polyether polyols, surfactants, catalysts, HCFC-141B 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.
