Dielectric constants of common materials materials deg.
Dielectric constant of plastic sheet.
It is also called as electric permittivity or simply permittivity.
In general low dielectric constants i e polypropylene result in a fast substrate while large dielectric constants i e alumina result in a slow substrate.
The dielectric constant dk of a plastic or dielectric or insulating material can be defined as the ratio of the charge stored in an insulating material placed between two metallic plates to the charge that can be stored when the insulating material is replaced by vacuum or air.
