INTRODUCTION
DonPanel 415/PIR is a compound which consists of polyols, surfactants, catalysts, and flame retardant , mixture of HFC-245fa as blowing agent in a special ratio. The foam has good thermal insulation property, light weight, high compression strength and flame retardant and other advantages. It is widely used to produce sandwich plates, corrugated panels etc, which applies to make cold stores, cabinets, portable shelters etc.
