What are the concepts and differences between thermoplastic resins and thermosetting resins?
Thermosetting resins undergo chemical changes after heating, which gradually hardens and hardens without being softened by heat.
The difference between them is that when the resin is heated, can the change be resumed after cooling, and the thermoplastic resin can be recovered, and the thermosetting resin can not be recovered.
Thermoplastic resin: it has the properties of heat softening and cooling hardening, and without chemical reaction, it can keep the performance no matter how many times the heating and cooling are repeated. All thermoplastic resins are linear in their molecular structure.
