KETJENBLACK EC-300J – Conductive Carbon Black
KETJENBLACK EC-300J is an ultra-pure, electro-conductive carbon black engineered for advanced antistatic and conductive applications across plastics, elastomers, and coatings. Due to its high specific surface area (~800 m²/g BET) and unique porous morphology, it delivers excellent conductivity at just one-third the loading of conventional conductive carbon blacks—making it the industry’s top choice where electrical performance and mechanical integrity must be balanced.
This material is particularly valued in sensitive polymers where lower filler content reduces impacts on mechanical strength, rheology, and processing ease.

| Appearance | Black, free-flowing pellets |
Key Features:
Achieves equal or better conductivity at ½–⅓ the loading of conventional carbon black
Minimally affects mechanical properties of base resins or coatings
Low ash content, ideal for semiconductor-grade cable shielding
Smooth processing with low grit content—excellent for extrusion and molding
Maintains conductivity when blended with other additives or pigments
Works across thermoplastics, thermosets, elastomers, and coatings
Applications:
KETJENBLACK EC-300J is suited for a wide range of conductive and antistatic applications, including:
Plastics and polymers (e.g., PP, PE, PVC, ABS, EVA, TPU)
Thermoset resins and epoxy systems
Conductive coatings and primers
Semiconductive cable shielding
Electrostatic discharge (ESD) packaging for IC components
Battery systems and electrode formulations
Flooring, carpet backing, tubing, and automotive parts
Consumer electronics (cell phones, laptop housings, etc.)
Note: The required loading levels vary based on resin type and conductivity targets.
Conductivity Mechanism:
The performance of KETJENBLACK EC-300J is driven by its interconnected pore structure and ultra-fine particle size, creating efficient conductive networks even at low loading levels. Its electron microscope-visible morphology confirms a high-density, chain-like structure that supports exceptional conductivity retention—even when combined with resins or additives.
Storage Recommendations:
Store KETJENBLACK EC-300J in a dry, well-ventilated area away from direct sunlight. Packaging integrity may degrade with extended UV exposure (over 30 minutes). Seal packaging when not in use to prevent moisture uptake.
Why Choose KETJENBLACK EC-300J?
Superior conductivity at reduced filler levels
Minimized impact on mechanical and rheological properties
