Product Description
Ketjenblack EC-300J is a high-purity, high-structure electroconductive carbon black engineered for antistatic and conductive compounding. With a very high BET surface area (approx. 800 m²/g), it delivers the same conductivity as conventional conductive blacks at roughly one-third the loading level — reducing filler content while preserving the mechanical and rheological properties of the base polymer. Evergreen Chemicals supplies Ketjenblack EC-300J in bulk and standard packaging for polymer compounders, cable & wire manufacturers, coatings formulators, and battery material producers across thermoset, thermoplastic, and elastomer systems.

| Applications | |
● Cable & wire semicon shielding — low ash content suits sensitive semicon compounds ● Conductive coatings & primers — optimal conductivity at very low loading ● Battery components — conductive additive for electrode/battery formulations ● Packaging for IC parts, tubing, flooring, carpet backing ● Automotive parts & consumer electronics (cell phone housings, etc.) ● Antistatic thermoplastics, thermosets, and elastomers — all polymer types For higher-conductivity requirements at even lower loading, see the related grade Ketjenblack EC-600JD, which achieves equivalent conductivity at roughly half the dosage of EC-300J. | |
