The Thermoset family of plastic materials harden and cure in the molding process as the molecules crosslink in a chemical reaction and set into a final shape. Additional heat will not soften or melt the material. As a result, thermosets are advantageous in any high heat environment where softening or melting cannot be tolerated. Domestically products, such as ashtrays, cooking utensils, and cookware handles are produced from thermosets. Thermosets are also used in electrical, electronic and military applications. Some examples of thermoset materials are phenolics, epoxies, melamines and diallyl phthalate.
