electrical and Dielectric properties  of composite films based on polyethylene

Metallurgy and Materials

The article is dedicated to the study of zeolite fine filler impact on the dielectric characteristics of high-density polyethylene. The author has researched the dependency of the charging and discharging currents in the range of temperatures (90-110)°C and analyzed the data obtained on the base of the Voigt equivalent circuit. Within low frequencies (10-1 – 10-4) Hz in parameters of the Voigt equivalent circuit, the electric characteristics are calculated both for the initial low pressure polyethylene and for that with additional filler. It is executed the calculation of one of the main technical characteristics of the film polymeric materials – ka absorption coefficient.
