Polyethylene (PE) is a thermoplastic polymer synthesized from ethylene monomers, representing one of the most widely produced and versatile commodity plastics. It is used across consumer, industrial, and structural applications due to its combination of low density, chemical resistance, ease of processing, and cost-effectiveness. PE is chosen by engineers when lightweight, corrosion-resistant, flexible materials are needed, and it often outperforms alternatives in applications requiring impact absorption and environmental durability at moderate temperatures.
