Vinyl Dielectric Constant

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

Vinyl dielectric constant.

Pvc offers excellent chemical and flame resistance strength to weight ratio and dielectric properties along with good tensile flexural and mechanical strength low moisture absorption and exceptional dimensional stability. 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. Values presented here are relative dielectric constants relative permittivities. Formulations typically include the pvc resin plasticizer stabilizer flame retardants fillers and specialty additives.

In addition it is easily altered by the addition of plasticizers impact modifiers and other ingredients. 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. Dielectrical constants of polymers.

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. Table of dielectric constants of polymers. 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.

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. Polyacetal poly methylene oxide pom. The capacitance created by the presence of the material is directly related to the dielectric constant of the material. Vinyl chloride resin soft 2 8.
