PET

Polyethylene terephthalate (engineering grade)

Engineering-grade PET, nucleated and glass-fibre reinforced, behaves like a stiffer, more heat-resistant sibling of PBT. Surface gloss and dimensional stability are good; electrical properties are close to PBT. Mould-temperature control is important for correct crystallisation.

Overview

PET is the standard grade of the PET family in the engineering plastics group. It is used in applications such as electric-motor and coil parts, headlamp reflectors and instrument parts, small-appliance handles and housings. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.

Tensile strength55–75 MPa
HDT (1.8 MPa)65–75 °C (takviyesiz)

Tensile strength is measured to ISO 527, melt flow rate to ISO 1133, heat deflection temperature to ISO 75 (1.8 MPa); flammability class per UL94. Depending on supplier and grade, values can fall outside this range.

Applications

  • Electric-motor and coil parts
  • Headlamp reflectors and instrument parts
  • Small-appliance handles and housings
  • Chair and furniture fittings

Documents

The supplier's technical data sheet (TDS) and safety data sheet (SDS) for PET are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
