PET Bar

A polyester material with a relatively high density.

PET has a unique combination of properties and has better wear and abrasion resistance than nylon or acetal, wet or dry. It also has significantly better dimensional stability and low thermal expansion rate plus good electrical properties.

Its superior chemical resistance, non staining characteristics, and distinct lack of centerline porosity, makes it a desirable material for a variety of applications especially in the food industry that might involve solvents, cleaning chemicals, or direct food contact.

Due to its good creep strength, low moisture absorption and outstanding dimensional stability, PET plastic material is extremely well suited for applications where complex parts and the highest requirements regarding dimensional accuracy and surface quality are needed. The thermal properties of PET support a good temperature stability as well as dimensional stability.
