INTRODUCTION

DonPanel 423 system is a four components system which consists of blend polyols, polymeric MDI, catalyst and blowing agent (pentane series). 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.
