Thermoset vs Thermoplastic: What’s the Difference, and Which One Does Your Part Need?
Thermoplastics and thermosets start as the same kind of raw resin but diverge permanently at the molding stage — one remains remeltable indefinitely, the other cures into a fixed structure it can never return from. This guide breaks down why that distinction happens at a molecular level, where it actually shows up in cost, recyclability, and heat resistance, and which material family fits most parts by default.
