polyetehylentereftalát

Polyethylene terephthalate, commonly abbreviated as PET or PETE, is a thermoplastic polymer resin of the polyester family. It is a clear, strong, and lightweight plastic that is widely used in packaging, fibers, and films.

PET is synthesized through the polymerization of ethylene glycol and terephthalic acid. The resulting polymer exhibits excellent barrier properties, making it ideal for containing liquids and gases. This characteristic contributes to its extensive use in beverage bottles, food containers, and pharmaceutical packaging.

In addition to its packaging applications, PET is also a significant material in the textile industry. When extruded into fibers, it forms polyester, a durable and widely used fabric known for its resistance to stretching and shrinking. These fibers are found in clothing, home furnishings, and industrial textiles.

PET is also recyclable. Post-consumer PET products can be collected, processed, and re-melted to create new items, such as bottles, fibers for carpets, or stuffing for pillows. This recyclability has made PET a focus of efforts to reduce plastic waste and promote a circular economy. Its chemical inertness, low melting point, and ability to be molded into various shapes further contribute to its versatility and widespread adoption across numerous industries.
