In the field of conductive materials, Ketjen Black stands out as one of the most efficient and widely used forms of electroconductive carbon black. Known for its extremely high structure and large specific surface area, Ketjen Black provides outstanding electrical conductivity at very low loadings, making it a preferred additive in advanced materials and energy applications.
What Is Ketjen Black?
Ketjen Black is a highly structured form of carbon black engineered to create efficient conductive networks within polymers, coatings, and adhesives. Compared with conventional carbon black, it offers:
- Higher electrical conductivity with minimal loading
- Excellent dispersion and processability in resin systems
- Improved thermal and chemical stability for demanding environments
Main Grades of Ketjen Black
Ketjenblack EC-300J
A reliable conductive carbon black used in antistatic and ESD applications. EC-300J provides a balanced combination of conductivity, processability, and surface smoothness, making it ideal for conductive coatings, films, and thermoplastics.
Ketjenblack EC-600JD
A highly structured, easy-to-disperse grade of Ketjen Black, designed for applications requiring maximum conductivity at low concentrations. EC-600JD is widely used in:
- Lithium-ion battery electrodes (to enhance charge transport)
- Conductive inks and coatings (for ESD and EMI shielding)
- High-performance polymer systems (requiring uniform dispersion and conductivity)
Key Applications of Ketjen Black
- Battery electrodes – Improves electron transport and charge efficiency
- Conductive plastics and rubbers – Provides stable antistatic performance
- Coatings and paints – Delivers uniform conductivity and surface resistance
- Adhesives and sealants – Enhances electrical properties without affecting flexibility
