WebThermosetting polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer ( resin ). [1] Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. WebProduct Name CAS NO.
