Vinyl Dielectric Constant

Multiply by ε 0 8 8542 x 10 12 f m permittivity of free space to obtain absolute permittivity.

Vinyl dielectric constant. Table of dielectric constants of polymers. The ratio between the actual material ability to carry an alternating current to the ability of vacuum to carry the current. Knowing the dielectric constant k of a material is needed to properly design and apply instruments such as level controls using radar rf admittance or capacitance technologies there are also analytical reasons to know the k of a material. Formulations typically include the pvc resin plasticizer stabilizer flame retardants fillers and specialty additives.

Dielectric constant is a measure of the charge retention capacity of a medium. Vinyl chloride resin hard 5 8 6 4. Flexible and transparent high dielectric constant polymer films based on molecular ferroelectric modified poly vinyl alcohol yunyun yang college of polymer science and materials the state key laboratory of polymer materials engineering sichuan university chengdu 610065 china. Vinyl chloride resin soft 2 8.

The formulation the dielectric constant can vary from 3 to 6. Values presented here are relative dielectric constants relative permittivities. As indicated by e r 1 00000 for a vacuum all values are relative to a vacuum. The dielectric constant or permittivity ε is a dimensionless constant that indicates how easy a material can be polarized by imposition of an electric field on an insulating material.

Dielectric constant k is a number relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current. The capacitance created by the presence of the material is directly related to the dielectric constant of the material. In addition it is easily altered by the addition of plasticizers impact modifiers and other ingredients. 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.
