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- 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 …
