The term engineering resin or engineering plastic usually refers only to thermoplastics, which can be molded and remolded to shape, and excludes thermosets such as epoxy resins that cure into an infusible solid. Some rubbers (e.g., polyurethanes) that are cured or vulcanized are nevertheless classed...
