PETG is an easily fabricated plastic

PETG

  • Durable and tough
  • Good chemical resistance
  • High impact strength
  • Good clarity
  • Easily formed, die-cut and punched

Characteristics

Easily formed, die-cut and punched, PETG is a solid choice for applications in which complex shapes, details, deep draws and compound curves are featured. It can also be painted, silk screened or hot stamped.

Exceptionally durable, PETG offers engineers great design freedom and is suitable for many applications. With better impact strength than acrylic and lower cost than polycarbonate, PETG is the superior choice for many complex fabrications.

Applications

  • Covers
  • Guards
  • Electronics
  • Medical braces
  • Point-of-purchase and graphic displays
