The properties of thermosets and thermoplastics are quite different—but the similarities and differences are often asked about. The primary difference in these two plastics comes down to heat and chemical resistance. Heat resistance is the primary function of a thermoset material, while thermoplastics—which are much more common—can only withstand heat to a certain degree. It’s worth noting that plastic injection molding companies typically do either thermoset or thermoplastic injection molding, but rarely do they handle both.
