PET, which stands for polyethylene terephthalate, is a clear, strong and lightweight plastic belonging to the polyester family. It is typically called "polyester" when used for fibers or fabrics, and "PET" or "PET Resin" when used for bottles, jars, containers and packaging applications. PET is the world's packaging choice for many foods and beverages because it is hygienic, strong, lightweight, shatterproof, and retains freshness. It is most commonly used to package carbonated soft drinks and water.
Polyethylene Terephthalate (PET) is basically produced by polymerization of ethylene glycol and terephthalic acid. Ethylene glycol and terephthalic acid are regarded as building blocks for PET resin. Further, these resins are heated to a molten liquid which can be easily molded into items of any shape.
Because Polyethylene Terephthalate is an excellent water and moisture barrier material, plastic bottles made from PET are widely used for mineral water and carbonated soft drinks
PET has wide applications in textile industry. 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.
Thanks to good electrical insulating properties, high structural and dimensional stability, polyethylene terephthalate is widely used in electrical and electronics industry. It 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.
