Also, visit our technical resources section 		Overview PBT is a strong, stiff engineering plastic with excellent machining characteristics, chemical resistance, and bearing and wear properties.

PBT is often used for food processing machinery applications when low moisture absorption, resistance to staining, or resistance to cleaning chemicals is required.
