What is Polyethylene?

Polyethylene is a thermoplastic polymer derived from the polymerization of ethylene monomers. It is also considered an addition polymer. It is characterized by a linear structure, consisting of repeating units with two hydrogen atoms attached to each carbon atom.

The linear and simple structure of Polyethylene polymer gives rise to its versatile properties, including flexibility, chemical resistance, and electrical insulating capabilities. With variations like Low-Density Polyethylene (LDPE) and High-Density Polyethylene (HDPE), polyethylene is employed in diverse applications such as packaging, containers, pipes, and medical devices.

Discovery of Polyethylene

Polyethylene was discovered by the German chemist Hans von Pechmann in 1898. However, its commercial production and recognition as a significant polymer began in the 1930s. Imperial Chemical Industries (ICI) in the United Kingdom developed a new method for manufacturing polyethylene in 1933, leading to the creation of low-density polyethylene (LDPE).

Polyethylene is an important thermoplastic polymer, it is abbreviated as PE and is a lightweight, durable, synthetic resin, that has a variety of uses. It is a polymer of ethylene hence the name polyethylene and is the most commonly used plastic. The chemical formula for polyethylene is (C₂H₄)_n. Polyethylene is also called, Polyethene, and Polythene.
