Polyethylene or polythene is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, etc.). As of 2017, over 100 million tons of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. PE is usually a mixture of similar polymers of ethylene, with various values of n. It can be low-density or high-density: low-density polyethylene is extruded using high pressure (1000?5000 atm) and high temperature (520 kelvins), while high-density polyethylene is extruded using low pressure (6?7 atm) and low temperature (333?343 K). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. Seaboard HDPE UV stabilized material has great scratch and impact resistance, and stiffness, yet is easy to fabricate and machine for the most demanding applications. It is ideal for outdoor cabinetry, furniture, signage, and recreational area applications.
