Dielectric Material

Published: | Updated: November 30, 2019

Definition - What does Dielectric Material mean?

Dielectric material refers to nonconductors or insulators in which an electric field can be sustained with a minimum dissipation of power. Unlike metals, no electricity flows in dielectrics when they are placed in an electric field. Instead, dielectric polarization occurs. This produces an internal electric field, reducing the overall electric field of the dielectric.

Dielectric materials are often used in shoes or eyewear for safety purposes.

Safeopedia explains Dielectric Material

Dielectric substances are normally solids, such as porcelain, mica, glass, plastics and the oxides of various metals. Some liquids and gases are also dielectric, including distilled water, nitrogen and dry air. Dielectrics are used for making capacitors, radio frequency transmission lines, camera flash systems and insulated footwear.
