Thermosetting and thermosoftening polymers

WebbThermosetting plastics and thermoplastics are both polymers, but they behave differently when exposed to heat. Thermoplastics can melt under heat after curing while thermoset plastics retain their form and stay solid under heat once cured. Do thermoplastics melt? Webb19 juni 2024 · Although there are many similarities between thermoplastic and thermoset, some differences are also present. The most common plastic polymers for the injection molding process were thermoplastic polymers. However, another type of plastic surfaced in the manufacturing industry – Thermosetting plastics.
