PBT (polybutylene terephthlate) is a polyester that has good chemical and impact resistance, a low coefficient of friction, moderate temperature resistance and outstanding machinability. It does not crack or craze in chlorine nor does it chip or contaminate food products. PBT is approved for direct food contact. Typical applications include food piston pumps, valves and valve bodies, timing screws, gears, cams, bushings and bearings, wear strips, fuel pump components, and fuel system connectors and rotors.
