Electrical insulation: As a result of its outstanding electrical insulating characteristics, polyethylene is usually used in Digital and electrical applications.
It will also be noted that lower-density polyethylene displays decreased crystallinity than significant-density polyethylene. The crystallinity of polythene is thought to range between 35% for reduced-density polyethylene to 80% for prime-density polyethylene.
bags with an equivalent body weight of freshly regenerated silica gel desiccant. With the Cambridge English Corpus These illustrations are from corpora and from sources on the web.

Plumbing and irrigation programs routinely use polyethylene pipes because of its overall flexibility, resistance to corrosion, and affordability compared to metal pipes. They're also used in sewage and gasoline distribution techniques.
Polymer structure: Polyethylene comprises repeating ethylene monomer models linked jointly through covalent bonds, forming prolonged chains or branches.
Polyethylene burns bit by bit with a blue flame aquiring a yellow idea and gives off an odour of paraffin (just like candle flame). The fabric continues burning on removing on the flame resource and generates a drip.[20]
Based on the polymerization procedure made use of, a variety of varieties of polyethylene with differing properties is usually acquired. They are categorized centered on their density, molecular body weight, and branching construction.
Examples are quickly compiled from on the web sources to show recent usage. Study More Viewpoints expressed while in the illustrations will not symbolize Those people of Merriam-Webster or its editors. Deliver us opinions. Plastic bottles, wafers, polythene bags, and vacant cigarette packs mark the route. —
