Bearing Grade PET-P (Polyethylene Terephthalate Polyester), is a thermoplastic polyester. With good dimensional stability, electrical properties, high strength, low water absorption, good chemical resistance (with the exception of alkalis) and low wear and friction capabilities, Bearing Grade PET-P offers a greater acidic resistance and stain resistance than Nylon or Acetal.
Applying Bearing Grade PET-P reduces the need for heavy lubrication, making the material useful for manifolds, distribution valves and pistons. The material is also lightweight and widely used for packaging material, electrical insulation and coatings within the Aerospace & Defense industry, as well as in food applications.
While Bearing Grade PET-P can be provided in FDA compliant grades, it should not be used for continuous use in hot water.
A wide range of extruded and compression molded shapes and sizes are available for machining. Some processing challenges may arise due to the uneven sizing of the rod diameter and plate thickness.
