PET

A strong, dimensionally stable plastic with outstanding chemical resistance and wear properties

PET (polyethylene terephthalate, semicrystalline) is a strong, stiff engineering plastic with excellent machining characteristics, chemical resistance, and bearing and wear properties. 

PET is often used for food processing machinery applications where low moisture absorption, low thermal expansion, resistance to staining, or resistance to cleaning chemicals is required.

FDA compliant grades of PET are available.

Tech Tip– PET is resistant to many CIP (clean in place) wash-down solutions.
