LLC "UKRSTARLINE" sells a wide range of rolled metal: black, galvanized, stainless, non-ferrous, as well as rubber products at competitive prices. Delivery is carried out quickly throughout Ukraine. We have an opportunity to deliver under the order or to make positions interesting the client. Send applications to viber (Kyivstar operator). Our professional managers are happy to advise each client. A dielectric is a substance that does not or does not conduct electricity well. The electrical properties of dielectrics are determined by their ability to polarize in an external electric field. The parameters of dielectrics determine their mechanical (elasticity, strength, hardness, viscosity), thermal (thermal expansion, heat capacity, thermal conductivity), electrical (electrical conductivity, polarization, energy absorption, electrical strength), magnetic, optical properties, and also determine their electrical, mechanical , thermal responses to the action of an electric field, mechanical stress, temperature. Dielectrics include various gases, liquids, for example, oils, glasses, various resins, plastics, etc.
The specific resistance of deionized water (see also: bidistillate) is 18 MΩ cm.
Dielectrics also include paraelectrics - nonlinear dielectrics that do not have spontaneous polarization, the relative permittivity of which decreases with increasing temperature (strontium, potassium, cadmium titanates; ferroelectrics above the Curie temperature).
A number of dielectrics exhibit interesting physical properties. These include electrets, piezoelectrics, pyroelectrics, ferroelastics, ferroelectrics, relaxors, and ferroelectrics.
