Thermosetting plastic: It is a polymer that irreversibly becomes rigid when heated. ... are plastics which will soften when heated and can be reshaped. Thermosetting plastics are plastics do not soften on ... 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.

Thermoplastic polymers melt when heated and become solid when cooled. But, thermosetting polymers chemically degrade when heated. However, thermosetting polymers are stronger and …
WebIt may also be used as an adhesive. Once hardened, a thermoset cannot be melted for reshaping, in contrast to thermoplastic polymers which are commonly produced and … WebThermoset polymers are distin-guished from elastomers and thermoplastic polymers in several ways. Thermoplastics are processed in the molten state, their final shape and internal structure established by cooling, and they can be sof-tened and reshaped by reapplica-tion of heat and pressure. Also, their polymer chains, whether lin-
