Ketjenblack EC-300J,Electroconductive carbon black 日本

Ketjenblack EC-300J is a very pure carbon black extremely suitable for antistatic and electroconductive applications. Due to its unique morphology and the very high surface area of approx. 800 m2/g (BET), only one third the amount of Ketjenblack EC-300J is needed compared to conventional electroconductive blacks in order to achieve the same conductivity. The lower loading of Ketjenblack EC-300J allows easier processing for those polymers sensitive to filler addition, thus minimizing loss in mechanical and rheological properties. Ketjenblack EC-300J when thoroughly dispersed with the polymer significantly increases the conductivity of the resulting compound. Ketjenblack EC-300J can be used in all types of polymers, thermoset, thermoplastic as well as elastomers. Due to its unique morphology and structure with relative low amounts of Ketjenblack EC-300J excellent conductive material can be made. The low grit content results in very smooth surfaces during extrusion. The loading needed to obtain a certain conductivity can vary significantly per type of polymer. More detailed information is provided in our special Ketjenblack EC Technical Bulletin. Ketjenblack EC-300J

has a very low ash content, which makes it the preferred material for semicon applications in cable shielding. Ketjenblack EC-300J can also be used to produce conductive coatings and primers. Also here already at very low loading levels optimal electroconductive performance is obtained minimizing loss in mechanical and rheological properties. Some other applications are batteries, packaging for IC parts, tubing, flooring, carpet backing, automotive parts, cell phones and many more. For even more demanding applications Ketjenblack EC-600JD is available of which about half the amount is needed to obtain the same conductivity as with Ketjenblack EC-300J.
