Polyethylene or polythene is a type of polyolefin. It is often abbreviated as PE. The chemical formula of PE is (C 2 H 4) n. It is lightweight, durable, and one of the most commonly produced plastic. Used for frozen food bags, bottles, cereal liners, yogurt containers, etc.
Chemical Properties. Polyethylene is made up of nonpolar saturated hydrocarbons with very high molecular weights. This is believed to be the reason why the chemical properties exhibited by polyethylene are quite similar to those of paraffin. It can be noted that the individual polyethylene macromolecules are not linked via covalent bonds.

Polyethylene is classified by its density and branching. Its mechanical properties depend significantly on variables such as the extent and type of branching, the crystal structure, and the molecular weight. There are several types of polyethylene: Ultra-high-molecular-weight polyethylene (UHMWPE)
Mar 28, 2024 · The chemical structure of polyethylene is composed of repeating monomers formed of hydrogen and carbon atoms. The general formula for polyethylene is represented by (C 2 H 4 )n. Heat can be used to remold the majority of polyethylene varieties, which are thermoplastic.
Characteristics of Polyethylene. Being one of the simplest polymers, polyethylene consists solely of carbon (C) and hydrogen (H) atoms. The simplest form of this polymer is seen in the high-density polyethylene (HDPE), characterized by a linear chain of carbon atoms, with hydrogen atoms attached to them.
