Ketjen Black EC-300J Conductive Carbon Black
KETJENBLACK is an electro-conductive carbon black known for exceptional performance and consistent quality. When mixed with plastics, rubber, or other materials, it achieves the same electro-conductivity as conventional carbon blacks but at significantly lower loadings.

Applications of Ketjenblack
Ketjenblack EC-300J is a highly pure conductive carbon black ideal for antistatic and electroconductive applications. Its unique morphology and high surface area (~800 m²/g BET) enable equivalent conductivity to conventional conductive blacks at one-third the loading. This reduced loading minimizes mechanical and rheological property loss in polymers sensitive to filler addition. When well dispersed, it significantly improves compound conductivity.
It is compatible with thermoplastics, thermosets, and elastomers, producing conductive materials at low loadings. Low grit content ensures smooth extrusion, and ash levels are suitable for semicon cable shielding. Additional uses include conductive coatings, primers, batteries, IC packaging, tubing, flooring, carpet backing, automotive components, and mobile device parts.
