Vinyl Dielectric Constant

Dielectric constant is a measure of the charge retention capacity of a medium.

Vinyl dielectric constant.

Multiply by ε 0 8 8542 x 10 12 f m permittivity of free space to obtain absolute permittivity. 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. Vinyl chloride resin soft 2 8. Dielectrical constants of polymers.

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. The formulation the dielectric constant can vary from 3 to 6. As indicated by e r 1 00000 for a vacuum all values are relative to a vacuum. 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.

Values presented here are relative dielectric constants relative permittivities. Formulations typically include the pvc resin plasticizer stabilizer flame retardants fillers and specialty additives. 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 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.

Vinyl chloride resin hard 5 8 6 4. Polyacetal poly methylene oxide pom. The ratio between the actual material ability to carry an alternating current to the ability of vacuum to carry the current. In addition it is easily altered by the addition of plasticizers impact modifiers and other ingredients.
