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). Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. Heat is not necessarily applied externally, but is often generated by the reaction of the resin with a cu… WebThe most common example of a thermosetting polymer is that of Bakelite, which is used in making electrical insulation. iv) Fibres: In the classification of polymers, these are a class of polymers which are a thread like in nature, and can easily be woven.
