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.

Thermosetting plastics are made up from long chains of molecules that are cross-linked. They have a very rigid structure.
