Poly(butylene terephthalate) is widely used in the automotive industry for manufacturing various components such as electrical connectors, sensor housings, and under-the-hood parts due to its excellent mechanical strength, heat resistance, and electrical insulation properties. In electronics, it is utilized for producing insulating parts, switches, and relay components because of its good dimensional stability and resistance to wear. The material is also employed in the production of fibers and textiles, offering durability and resistance to chemicals and abrasion. Additionally, it finds applications in household appliances, such as in the fabrication of handles, knobs, and other parts that require high impact resistance and thermal stability. Its ease of processing through injection molding makes it a preferred choice for creating complex shapes and designs in various industrial applications.
