Polyester, PET, PBT For Dummies. AKA, For The Beginner

*Why use Polyester:

Very Stiff Material – High strength
Superior Wear Resistance
230ºF Continuous Use Temperature
Very Low Moisture Absorption
Improved UV Resistance Compared to Acetal or Nylon
Easily Machined and Fabricated

This materials is…

excellent wearing and very abrasion resistant. PET is an non-reinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate. The low moisture absorption and low rate of thermal expansion make it ideal for demanding applications that require close tolerance.

Good Machining Properties
FDA, USDA and 3-A Dairy Compliant
Superior Wear Resistance
Chemically Resistant to Chlorine and Caustic/Acidic Cleaning Agents
Offers excellent strength, rigidity and machinability

This material is used frequently in a self lubricating bearing surface or slide type applications. Resistant to most common chemicals. Commonly replaces Aluminum, Acetals and Nylons. Used frequently in Food and Dairy Processing, Material Handling, Fluid Handling and Automotive. Other brand or trade names are: Ertalyte®, Ensitep®, Hydex®, Sustadur®, Tecapet®, Celanex®, Duranex®, Ultradur®, Valox®, Rynite®, and Hostadur®.
