Many researches are being conducted on conductive plastic for use for static electricity prevention and electromagnetic shielding. The aim of this study is to fabricate a power circuit which allows flow of current to a considerable extent using compression molded conductive plastic. First, to minimize the electric resistance of the conductive plastic, experimentations were carried out on the volume resistivity and formability of a compression molded product containing a high amount of short

In the experiment, the composition was adjusted using commercially available conductive materials. We also studied the heat generation characteristics by passing about 10 ampere current through the compression molded material.
