What is the electrical conductivity of Teflon?

Teflon, or polytetrafluoroethylene (PTFE), is known for its Excellent insulating properties and is considered an electrical insulator. Its electrical conductivity is extremely low, typically in the range of 10^-16 to 10^-18 S/m, making it unsuitable for applications requiring electrical conduction. This property is one of the reasons Teflon is widely used in electrical insulation and as a non-stick coating.
