PET - Polyethylene Terephthalate

PET has good barrier properties against oxygen and carbon dioxide. Therefore, it is utilized in bottles for mineral water. Other applications include food trays for oven use, roasting bags, audio/video tapes as well as mechanical components.

 

Textile Grade: Textile-grade polyester chips are used for making the Polyester Filament yarn like POY, FDY and Staple fibre...       ...more     Bottle Grade: The Bottle grade chips are used in Mineral Water Bottle grade and CSD grade (soda grade) varieties, distilled water, drinking water, flavoring and candy containers, PET sheet material...       ...more     Film Grade: The Film grade polyester chips are commonly available in Super Bright and Additive (Silica) varieties.       ...more

PET exists both as an amorphous (transparent) and as a semi-crystalline (opaque and white) thermoplastic material. Generally, it has good resistance to mineral oils, solvents and acids but not to bases.

The semi-crystalline PET has good strength, ductility, stiffness and hardness. The amorphous PET has better ductility but less stiffness and hardness.
