Sep 18, 2017 · Thermosetting polymer. A thermosetting polymer also called a thermoset, is a polymer that is irreversibly cured of a soft solid or viscous liquid prepolymer or resin. The process of curing changes the resin into an infusible, insoluble polymer network, and is induced by the action of heat or suitable radiation often under high pressure, or by mixing with a catalyst.
