Ketjenblack EC-300J

Supplied byNouryon- Last Updated on Apr 30, 2026

Ketjenblack EC-300J by Nouryon is a conductive carbon black with minimum impact on mechanical properties. It is extremely suitable for antistatic and electroconductive applications.
  • The lower loading allows easier processing for those polymers sensitive to filler addition, thus minimizing loss in mechanical and rheological properties.
  • When it is thoroughly dispersed with the polymer, it significantly increases the conductivity of the resulting compound.
  • It can be used in all types of polymers, thermoset, thermoplastic as well as elastomers.
  • It possesses very low ash content, which makes it the preferred material for semicon applications in cable shielding.
  • Recommended for batteries, packaging for IC parts, tubing, flooring, carpet backing, automotive parts and cell phones.
  • Ketjenblack EC-300J has a shelf-life of 12 months.
