Скачать или смотреть Electrical Properties of Everflon Fluoroplastic PFA

Electrical applications include extruded coatings for numerous wire constructions, heater cables, heavy wall conduit, cable jacketing, and geophysical cables. Everflon PFA fluoropolymer resins are also injection molded into electrical switch components, connector inserts, insulating bushings, and standoff insulators.
Dielectric constant and dielectric tangent
The dielectric constant of Everflon PFA resins is less than 2.1 over a wide range of frequencies, temperatures, and densities.
The values for Everflon PFA fluoropolymer resins density vary only slightly, and the dielectric constant varies only about 0.03 units over this range among the lowest of all solid materials. There is no measurable effect of humidity on the dielectric constant of Everflon PFA fluoropolymer resins.
Dielectric Strength
The dielectric strength (short-term) of all Everflon PFA fluoropolymer resins is 80 kV/mm when measured by ASTM D149.
Thin films of F E P resin give similar results, while PTFE films are typically measured at 47 kV/mm .
