Polyethylene terephthalate is a common thermoplastic polymer resin from polyester family. PET is safety material for food, beverage, and pharmaceutical application and also recyclable. Polyester resins are known for their excellent combination of properties such as mechanical, thermal, chemical resistance as well as dimensional stability. PET contains ethylene glycol and terephthalic acid, which are combined to form a polymer chain.
It is very strong and lightweight & hence easy and efficient to transport
It is known for its good gas (oxygen, carbon dioxide) and moisture barrier properties
It exhibits excellent electrical insulating properties
It has low gas permeability, in particularly with carbon dioxide
PET is suitable for transparent applications, when quenching during processing
PET doesn’t not break or fracture. It is practically shatter-resistant and hence, a suitable glass-replacement in some applications
It is recyclable and transparent to microwave radiation
PET is approved as safe for contact with foods and beverages by the FDA, Health Canada, EFSA & other health agencies
PET is widely used in packaging, containers for liquids and foods, fibres for clothing, and in combination with glass fibre for engineering resins.
Textiles: Polyester fabrics are strong, flexible, and offer additional benefit of less wrinkles and shrinkage over cotton. Polyester fabrics are light-weight, reduced-wind, drag-resistant and more resistant to tears.
Electrical and electronics: Thanks to good electrical insulating properties, high structural and dimensional stability, polyethylene terephthalate is an effective polymer to replace die casts metals and thermosets in applications like: electrical encapsulation, solenoids, smart meters, photovoltaic parts, solar junction boxes, etc. Polymer’s outstanding flow characteristics enable design freedom and miniaturization to produce high-performance parts.
Automotives: It is currently being employed in the following applications: wiper arm and gear housings, headlamp retainer, engine cover, connector housings.
