Editing Polyethylene (section)

===Electrical===
Polyethylene is a good [[insulator (electricity)|electrical insulator]]. It offers good [[electrical treeing]] resistance; however, it becomes easily [[triboelectric effect|electrostatically charged]] (which can be reduced by additions of [[graphite]], [[carbon black]] or [[antistatic agent]]s).
When pure, the [[dielectric constant]] is in the range 2.2 to 2.4 depending on the density<ref>{{cite web |title=Electrical Properties of Plastic Materials |url=https://www.professionalplastics.com/professionalplastics/ElectricalPropertiesofPlastics.pdf |website=professionalplastics.com |publisher=Professional Plastics |access-date=11 October 2022 |archive-url=https://web.archive.org/web/20220920173045/https://www.professionalplastics.com/professionalplastics/ElectricalPropertiesofPlastics.pdf |archive-date=20 September 2022 |language=en-US |url-status=live}}</ref> and the loss tangent is very low, making it a good dielectric for building [[capacitor]]s. For the same reason it is commonly used as the insulation material for high-frequency coaxial and twisted pair cables.
