SURFACE TREATED CARBON BLACK, PLASTICS AND RUBBER COMPOSITIONS CONTAINING THE SAME

摘要

This invention relates to a method where carbon black (CB) is surface treated by means of an active processing aid (APA), which is an additive for surface treating carbon black to induce amphipathic properties. More specific, the invention relates to CB having been pre-treated with an APA as surface lubricants such as organosilanes or fluorosilicones, stabilisators, anti-static aids or silicon lubricants which in blends with plastic or rubber compounds improves the processing rheology. Further, it relates to surface treated CB (STCB) giving UV, anti-static, semiconductive and conductive properties in plastic and rubber compounds without altering any mechanical or electrical properties in the plastic and rubber compounds.
