Determination of Electrophysical Characteristics of a Polymer Composite Material

This paper presents the results of an experimental determination of electrophysical characteristics such as the permittivity and dielectric loss tangent of a three-dimensional cross-linked plasticized polymer composite material based on low- molecular-weight rubbers filled with solid dispersed fillers. The measurement technique is described and the experimental results are analyzed. The dependence of the thermal energy density absorbed by the material on the time of microwave irradiation is calculated.
