Teflon wire insulation resins offer remarkable electrical stability

Teflon, TFE and FEP-fluorocarbon resins offer remarkable electrical stability over a wide range of frequency and environmental conditions.  In this respect, they differ markedly from other insulating materials.  The dielectric constant of TFE resins shows less change over a wide range of temperatures and frequencies than any other solid material.  Its dielectric strength is high and does not vary with temperature and thermal aging.
