Unfilled grades are tough and flexible. Good resistance to fuels, oils, fats, and many solvents. Doesn’t absorb flavors. Low creep.	Slide bearings, gears and cams; coffee makers and toasters; hair dryer nozzles; vacuum cleaners; handles and knobs for electrical cookers.	Glass-filled PBT resins are prone to warp, and have poor resistance to acids, bases, and hydrocarbons. Thin parts hard to fill with PBT. Nylons are good alternatives.
PET (Polyethylene Terephtalate)	similar to PBT, but stiffer and higher melting point	similar to PBT	similar to pbt
LCP	very easy flowing, good chemical resistance, high upper use temp, good electrical properties, low thermal expansion	connectors, plugs, PCBs, sports equipment	anisotropic properties and shrinkage, expensive
PPO	good electrical insulator, hot water / steam resistance	sensor housings, pumps, connectors	susceptible to stress cracking
PPS	very good chemical resistance, high upper use temp, great electrical properties	electric components, automotive intakes / pumps / valves / sensor encapsulation	desirable properties, such as chemical resistance rely heavily on proper crystallization during molding
