POLYETHYLENETEREPHTHALATE Meaning and Definition

  1. Polyethylene terephthalate, commonly abbreviated as PET, is a thermoplastic polymer and a type of polyester. It is a clear, lightweight, and flexible material that is widely used in the production of various products, including bottles, fibers, films, and packaging materials.

    Polyethylene terephthalate is composed of repeating units of ethylene terephthalate, a monomer composed of two rings: one of ethylene and the other of terephthalic acid. This combination gives PET its unique properties such as high strength, resistance to impact, and excellent chemical resistance.

    PET is commonly recognized for its use in the manufacturing of plastic bottles, which are preferred due to their durability and low production cost compared to other materials. It is also widely used in the textile industry for the production of polyester fibers and fabrics, known for their wrinkle resistance, durability, and quick drying characteristics.

    Furthermore, PET is highly recyclable, making it an environmentally friendly choice in the plastics industry. The recycled PET, known as rPET, can be used to produce new products, reducing the demand for virgin materials and minimizing waste.

    Overall, polyethylene terephthalate is a versatile polymer that offers a wide range of applications due to its exceptional properties, making it one of the most commonly used plastics worldwide.

Etymology of POLYETHYLENETEREPHTHALATE

The word "polyethyleneterephthalate" is derived from two main components: "polyethylene" and "terephthalate".

"Polyethylene" comes from the combination of two terms: "poly-" meaning "many" and "-ethylene" referring to a type of organic compound called "ethylene". Ethylene is a simple hydrocarbon molecule with the chemical formula C2H4.

"Terephthalate" is derived from the term "terephthalic acid", which is a white crystalline solid used in the production of polyester fibers, films, and plastic bottles. The term "terephthalic" comes from the combination of "terephthaloyl" and "-ic". "Terephthaloyl" represents a common fragment in organic chemistry, while "-ic" is a suffix used to indicate that the combined unit is an acid.
