Polyethylene terephthalate (PET) is a robust, rigid engineering thermoplastic belonging to the polyester family. Exhibiting exceptional machining capabilities, bearing, and wear properties, PET plastic combines lightness, strength, and impact resistance. Its low moisture absorption, minimal thermal expansion, and chemical resistance make PET suitable for food processing machinery and other applications requiring dimensional stability in varying conditions. In summary, PET’s unique blend of characteristics renders it an effective material choice for diverse engineering applications.

FAQs About PET


PET is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins. PET consists of repeating (C10H8O4) units. PET is commonly recycled, and has the digit 1 as its resin identification code.
