What Is an Unsaturated Resin Reactor: UPR Process, Design and Applications Answering the core question: What is an unsaturated resin reactor? An unsaturated resin reactor is a heated, agitated vessel, normally 316L stainless steel and fitted with a fractionating column and a condenser, in which unsaturated polyester resin is produced in two distinct stages. First, polycondensation: a dibasic acid blend of maleic anhydride and phthalic anhydride or isophthalic acid is reacted
