Question

what is thermosetting plastic??
​

Answer 1

${\huge{\sf{\blue{\underline{\underline{ ❥Aɳʂɯҽɾ }}}}}}$

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.

Answer 2

A plastic which once set,does not become soft on heating and cannot be moulded a second time,is called thermosetting plastic. Once set in a given shape and solidified,a thermosetting plastic cannot be re-softened or re-moulded. They are known as thermosets. They are hard and rigid.
