Properties of Teflon: Unique Electrical Properties

DuPont Teflon® industrial coatings are highly durable and long lasting performance coatings that have a distinct application process and qualities that offer solutions in a variety of industrial markets.   This series of blogs will highlight one of these inherent properties of Teflon®  coatings and how these properties can solve a variety of problems. 

Unique Electrical Properties: Over a wide range of frequencies, DuPont™ Teflon® industrial coatings have a high dielectric strength, low dissipation factor, and high surface resistivity.  Dielectric strength is the highest voltage that the coating can withstand before it breaks down. The low dissipation factor means that the absorbed energy dissipated as heat is low. PFA and ETFE have the highest dielectric strength at almost 2,000 volts per mil. However, in order to achieve these results, the coatings must be completely pinhole-free, so multiple coats are usually recommended.
