Electrical properties of pure PVC

摘要

Electrical properties of PVC are of great interest because of their wide electrical applications, and which can be considered as one of the easily molded insulators. The electrical properties of PVC depends not only on the chemical composition and structural features but also on the degree of molecular order. The dielectric investigations provide a fundamental method for studying the rotational and hopping of electrons processes involved in materials and account for the dispersion behaviour associated with molecular configuration and its ordering as it affects the conductivity behaviour. In the present work the Egyptian brand with K value 67 from Al-Amria Petro-Chemical Co. is being studied. Dielectric properties and loss factors together with electrical conductivity at different temperatures and frequencies are given.
