What is volumetric resistivity?
Volume resistivity is the resistance to leakage current through the body of an insulating material. The higher the surface/volume resistivity, the lower the leakage current and the less conductive the material is.
Is Teflon electrically conductive?
This makes it an excellent material for coating machine parts which are subjected to heat, wear, and friction, therefore the first choice for most enigineering solutions. PTFE has low electrical conductivity, so it makes a good electrical insulator.
How do you calculate volume resistance?
Volume resistivity was calculated by the following equation: Volume resistivity (µΩ∙cm) = [measured bulk resistance (µΩ) x line width (0.2cm) x line height (cm)] / line length (2cm). Contact resistance was measured using the transmission line method.

Why is Teflon a good insulator?
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.
What is the resistivity of Teflon FEP?
Volume Resistivity Volume resistivity of Teflon™FEP film decreases slightly as the film thickness increases (see Figure 11). Insulation Resistance Even at 200 °C (392 °F), the insulation resistance of Teflon™FEP film (65,000 Mohm·µF) is higher than most conventional dielectric materials at room temperature (see Figure 12).
What are the properties of Teflon?
Teflon® – a polytetrafluoroethylene – has outstanding dielectric properties that remain stable with frequency and temperature. It resists ignition and does not promote the spread of flames. Teflon® has a uniquely high bulk density. Characteristics include: Excellent thermal and electrical insulation properties; Low coefficient of friction
How does temperature affect Teflon™PTFE resin?
A transition occurs in Teflon™PTFE fluoropolymer resin, resulting in a 1–1.5% increase in volume as temperature is increased through the neighborhood of 19 °C (66 °F). This must be considered when measuring a part for a critical application. Measuring Tolerances Personnel should exercise caution when measuring
