The places where light is generated also generate heat, so most lamps use PBT plastic, which has the advantages of high heat resistance, good stiffness, and dimensional stability. Typical application examples include energy-saving lamp housings, power adapters, sockets, bases, and various lamp housings. For example, energy-saving lamp sockets are made of fiberglass reinforced flame-retardant PBT engineering plastic, which requires heat resistance, UV resistance, and UL94 V-0 flame retardancy. Lamp sockets are made of fiberglass reinforced PBT, which requires heat resistance and dimensional stability.

PBT engineering plastics have been used in a large number of household appliances for many years, some as shells and some as functional components. This is because PBT engineering plastics have high thermal deformation temperature and mechanical strength, good electrical insulation, stable size, and low moisture absorption. In addition, PBT process plastics have resistance to cleaning agents and cleansers, oils and fats, fruit and vegetable juices, food, carbonated soft drinks, and various seasonings. PBT engineering plastics are widely used in the manufacturing of electric iron handles, deep frying pan components, knife and scissors handles, hair dryer components, furnace door handles, knobs and panels, coffee pot utensils and bases, food processing shredder components, vacuum cleaner components, and toaster components.

Other application fields require PBT engineering plastics with special performance, especially elastomeric modified PBT engineering plastics, which can be used for winter sports equipment. It requires low-temperature impact and notch impact strength to ensure the usability of the components. Typical application examples include cabin drainage pumps. Textile framework and bobbin, spray nozzle, hot melt adhesive spray gun, hair dryer, ski connector components, ski shoe adjuster, etc.
