ABSTRACT:
A conductive molding composition for the compression molding of high density information discs (video discs). The composition includes a polyvinylchloride-based resin containing sufficient carbon black particles to obtain a desired conductivity (bulk resistivity of about 500 ohm-cm at 900 mHz or less,) from about 1 to 5 weight percent of a stabilizer, from about 0.5 to 3 weight percent of a lubricant, from about 1 to 5 weight percent of a plasticizer and from about 0.1 to 1 weight percent of an organo-silicone compound having polar groups.
