Description

Polyethylene Terephthalate – known as PET or Polyester– is a thermoplastic polymer that can be amorphous, crystalline, or a mixture of both, depending on how it is processed. All forms provide good chemical resistance and durability. Polymershapes offers a wide selection of polyester in sheet, film, rod and tube.

Polyester is known for having high dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture. These properties make it especially suitable for the manufacture of precision mechanical parts which must sustain high loads and endure persistent wear. Polyester is available in FDA, UDSA, 3A-Dairy and Canada AG compliant grades for a broad range of applications, making it an excellent candidate for parts used in food processing equipment.
