PET is the acronym for Polyethylene Terephthalate. PET is a clear, strong, lightweight plastic that is the most commonly used thermoplastic polymer in the world. It is produced from the synthesis of ethylene glycol and terephthalic acid. Even without additives to increase its strength, PET is still very strong for its lightweight.
The majority of the world’s PET production is for synthetic fibres, with bottle production accounting for about 30% of global demand. In the textile applications industry, PET is referred to by its common name, polyester. Whereas the acronym PET is generally used in relation to packaging and bottles mainly. Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after PE, PP and PVC.
PET is Highly flexible, colourless and semi-crystalline resin in its natural state. Depending upon the processing method, it can be semi-rigid to rigid. PET shows good dimensional stability, resistance to impact, moisture, alcohols and solvents.
