Method for the production of electrically conductive thermoplastics, and their use in the electrical industry

Abstract

Abstract 1. A process for molding small thermoplastic articles which, on the outside, contain conductive additives in highly concentrated form but on the inside comprise substantially additive-free thermoplastic into moldings having electroconductivities of not less than 0.001 S/cm with substantial retention of the inhomogeneous structure of the additive-free and additive-containing thermoplastic arrangement, which comprises heating up the thermoplastic particles without employment of pressure until the thermoplastic melts and moving the resulting melt under pressure inside a mold element using a flow rate from 5 to 150 m/hour and a low shear rate.
