Explanation:
A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin.
Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.
