HDPE – high density polyethylene is a thermoplastic material with a density of 0.941 g cm3 or greater. It is known for its low degree of branching, which leads to stronger intermolecular forces and higher tensile strength. HDPE can be manufactured using chromium silica catalysts, ziegler-natta catalysts, or metallocene catalysts, with the lack of branching being controlled by the specific catalyst and reaction conditions chosen.

HDPE finds wide use in various products and packaging, including milk jugs, detergent bottles, margarine tubs, garbage containers, and water pipes. As a polyethylene thermoplastic, HDPE is derived from petroleum and requires approximately 1.75 kilograms of petroleum (in terms of energy and raw materials) to produce one kilogram of HDPE. Additionally, HDPE is commonly recycled, with its recycling symbol being the number \
