Material Notes:
ENSACO™ & SUPER P™ conductive carbon blacks are carbon blacks with a high to very high void volume allowing the retention of a carbon network at low to very low filler content. The void volume can originate from the interstices between the carbon black particle due to their complex arrangement and from the porosity.PROPERTIES:High Structure / Low Surface AreaSoft flakesLow oxygen contentHigh purityHigh graphiticityPERFORMANCEElectrical conductivityExcellent dispersionLow viscosity increaseLow cure inhibitionEasy mixing and processingSome thermal conductivityMeets the most stringent purity requirementsFINAL APPLICATIONS: Automotive fuel hoses, transmission belts, conveyor belts, power cable accessories, thin membranes with high shock resistance, conductive profiles and seals, antistatic flooring, rollers, roller covering… Suitable for all rubber types including silicones and fluoroelastomersInformation provided by TIMCAL
