Dielectric constant of plastic sheet.

Values presented here are relative dielectric constants relative permittivities. F dielectric constant abs resin lump 2 4 4 1 abs resin pellet 1 5 2 5 acenaphthene 70 3 acetal 70 3 6 acetal bromide 16 5 acetal doxime 68 3 4 acetaldehyde 41 21 8 acetamide 68 4 acetamide 180 59 acetamide 41 acetanilide 71 2 9 acetic acid 68 6 2 acetic acid 36 degrees f 36 4 1 acetic. As indicated by e r 1 00000 for a vacuum all values are relative to a vacuum. The relative permittivity or dielectric constant of a material is its absolute permittivity expressed as a ratio relative to the vacuum permittivity.

Multiply by ε 0 8 8542 x 10 12 f m permittivity of free space to obtain absolute permittivity. Relative permittivity is the factor by which the electric field between the charges is decreased relative to vacuum. It is also called as electric permittivity or simply permittivity. 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.

Dielectric constant is a measure of the charge retention capacity of a medium. Permittivity is a material property that affects the coulomb force between two point charges in the material. Volts 0 001 0 001 0 005 1khz. Dielectric constants of common materials materials deg.
