polyethylentereftalaatti

Polyethylentereftalaatti, commonly known as PET or PETE, is a thermoplastic polymer resin of the polyester family. It is a versatile material widely used in packaging, fibers, and films. PET is formed through the polymerization of ethylene glycol and terephthalic acid. Its chemical structure provides it with a combination of desirable properties, including strength, rigidity, clarity, and good barrier properties against gases and moisture.

One of the most prominent applications of PET is in the production of beverage bottles. Its transparency allows consumers to see the product inside, while its strength prevents leakage and maintains carbonation. PET is also extensively used for food packaging, such as containers for ready meals and fruit trays. Beyond packaging, PET finds significant use in the textile industry, where it is spun into polyester fibers. These fibers are used to make clothing, carpets, and other fabrics due to their durability, wrinkle resistance, and quick-drying nature. PET films are also employed in various applications, including photographic films, magnetic tape, and electrical insulation.

PET is highly recyclable, contributing to its sustainability. Recycled PET can be used to create new bottles, fibers, and other products, reducing the need for virgin plastic production and diverting waste from landfills. The development of efficient recycling processes has made PET a cornerstone of many circular economy initiatives.
