Examples of Electro-Conductive and Mechanical Properties

KETJENBLACK is a unique electro-conductive carbon black that has received favorable evaluations for its superior performance and stability of quality. Mixed with plastic, rubber or other materials, KETJENBLACK has garnered high marks for providing the same level of electro-conductivity with a lower loading quantity as conventional carbon black.

(1) Same level of electro-conductivity as conventional carbon black but with 1/2 to 1/3 of the loading quantity

(2) Effective at a lower loading quantity, has minimal effect on the physical properties of base resins or paint

(3) Minimal reduction in electro-conductivity when mixed with other materials
