Capacitance electronic disc molding composition

摘要

A conductive molding composition for the preparation of high density capacitance electronic discs is disclosed. The improved composition contains only five ingredients and is characterized by superior playback without the necessity of washing the disc after pressing. The subject compositions contain as a dispersant isopropyl tri(dioctylpyrophosphato)titanate. Preferred compositions are additionally comprised of poly(vinyl chloride), conductive carbon black, diundecyl phalthalate as a plasticizer and a tin mercaptoester or tin alkyl mercaptide stabilizer.
