Why you should use Polyester:
- Very Stiff Material – High strength
- Superior Wear Resistance
- 230ºF Continuous Use Temperature
- Very Low Moisture Absorption
- Improved UV Resistance Compared to ABS, Acetal/Delrin 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
Applications – Frequently used in:
- Food Equipment and Dairy Processing
- Wear and Slide machined parts
- Electronics Manufacturing and Fixtures
- Pistons, Manifolds, Timing Screws, Scraper Blades
- Food Processing Forming Dies

“For years we used Delrin rod for our parts, but we always had some rejections due to breakage during machining. We changed to the PET rod, and the problem has vanished. Thanks” – Wayne P.
“This material seems to be as easy to machine as Acetal or Delrin. We like the finish better.” – Johnny G.
