Typical Properties
PET (semi-crystalline thermoplastic) is a strong, stiff engineering plastic with excellent machining characteristics, chemical resistance, and bearing and wear properties.

PET is often used for food processing machinery applications where low moisture absorption, low thermal expansion, resistance to staining, or resistance to cleaning chemicals is required.

PET Standard Sizes

SHEET 24"x48" (0.25"-4.0" thick)
ROD diameter 0.25"-6.0"

  • Length, width, thickness, and diameter tolerances vary by size and by manufacturer
  • Custom sizes and colors available upon request
  • Many of our plastic materials are available as films with thicknesses of 0.029" or less

PET Grades

  • Internally lubricated
