  • Though thermoset plastics and thermoplastics sound similar, they have very different Thermoset plastics contain polymers that cross-link together during the. The terms thermoplastic and thermoset describe the processability of a material as the temperature is changed. A polymer that becomes plastic and flows on heating, either by reason of crystal melting or by exceeding the glass transition temperature Tg is thermoplastic. Thermoplastics and thermosetting plastics are two separate classes of polymers, which are differentiated based on their behavior in the.
