Ketjenblack - Superconductive Carbon Black

Ketjenblack superconductive carbon black offers the highest electrical conductivity at the lowest concentration in the industry.

Due to their unique morphology, substantially lower amounts of Ketjenblack EC-300J, and even lower amounts of Ketjenblack EC-600JD, are needed to obtain the desired properties when compared to conventional carbon blacks. As a result, the processing and mechanical properties of the final product are much less impacted.

Ketjenblack can be applied to all types of polymers and elastomers and are used in a wide variety of applications including protective packaging for electronics, safety shoes, fuel tanks and hoses, conductive flooring, high voltage cables, batteries, fuel cells and conductive paint.
