Teflon® is a registered trademark name for the material polytetrafluoroethylene (PTFE). This synthetic fluoropolymer is one of the most popular insulating compounds. PTFE can withstand extreme temperature fluctuations between -90 °C to 260 °C and is used in many challenging environments.
Teflon® also displays excellent dielectric strength, making it an excellent electrical insulator. Teflon® coated components are very low friction, meaning components will experience minimal resistance.
