The combination of high mechanical and electrical properties, good thermal stability and superior chemical resistance creates many automotive application opportunities for both PBT and PBT alloys.
PBT can be found in both automotive exterior and interior parts and most particularly, in auto electrical system components.
Typical examples include windshield wiper covers, mirror housings, cowl vents, handles, fans, fuel system components, connectors, sensor housings, fuse boxes, actuator cases, power relays, switches, motor components, and ignition system components.
PBT alloys are most commonly used in body exterior and safety applications including airbag covers and containers brake and fuel line clips, cable liners, and power distribution boxes.

Industrial PBT Typical Applications:
Typically, industrial applications call for rugged parts capable of delivering long service life, often under harsh service conditions.
Among the diverse examples for PBT are fluorescent lamp bases, street lamp reflectors, pump housings and impellers, filter media, monofilaments, and packaging components.

PBT Alloys Typical Applications:
With the added dimension of high toughness, PBT alloys have been employed in air filter housings, small off-road fuel tanks, tractor hoods and panels, power tool housings and conveyor chain components.

Consumer Goods
Many consumer applications have benefited from the versatility of PBT-based resins,
particularly those calling for durability and involving some exposure to higher temperatures or electrical stresses, such as may commonly be found in small handheld appliances and tools.
PBT Typical Applications:
For PBT, typical applications include iron handles and bases, oven door handles, housings,
motor brackets and closure panels. Because of its performance and appearance,
PBT components can also be found on office furniture.
PBT Alloys Typical Applications:
Polyester alloys deliver toughness in such parts as are likely to be subject to impact and rough handling including appliance lids, closure
and kick panels, covers, and seat backs and bottoms. In consumer recreation uses,
PBT alloys appear in ski tops, ski boots, jet ski hulls and snowmobile and golf cart cowls.
