Applications

Ketjenblack EC-600JD is a very pure carbon black extremely suitable for antistatic and electroconductive applications. Due to its unique morphology and the extremely high surface area of approx. 1400 m2/g (BET), only one sixth the amount of Ketjenblack EC600-JD is needed compared to conventional electroconductive blacks in order to achieve the same conductivity. The extreme low loading of Ketjenblack EC600-JD allows easier processing for those compounds sensitive to filler addition, thus minimizing loss in mechanical and rheological properties. Ketjenblack EC-600JD when thoroughly dispersed with the polymer significantly increases the conductivity of the resulting compound. Ketjenblack EC-600JD can be used in all types of polymers, thermoset, thermoplastic as well as elastomers. Due to its unique morphology and structure with very low amounts of Ketjenblack EC-600JD excellent conductive material can be made. The loading needed to obtain a certain conductivity can vary significantly per type of polymer. More detailed information is available in the special Ketjenblack EC Technical Bulletin. Ketjenblack EC-600JD has a low ash content, which in addition with the extreme low loading level, makes it an excellent product for semicon applications in cable shielding. The low grit content provides very smooth surface during extrusion. Ketjenblack EC-600JD can also be used to produce conductive coatings and primers. Also here already at very low loading levels optimal electroconductive performance is obtained, which even more minimizes loss in mechanical and rheological properties compared to Ketjenblack EC-300J. With Ketjenblack EC-300J about double the amount is needed to obtain the same conductivity Some other applications are batteries, packaging for IC parts, tubing, flooring, carpet backing, automotive parts, cell phones and many more.
