thermosetting polymer

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. it results in chemical reactions that create extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network. the starting material for making thermosets is usually malle
