Rationale

Post-milling of rCB base char is a critical process which influences application performance. As traditional techniques employed for carbon black particle sizing have been found to be an unreliable measure of application performance, a need exists for an alternative particle sizing approach to monitor a base char milling process. Although particle sizing techniques are currently being employed by rCB manufacturers, their use is currently limited due to the lack of test method standardization. The utilization of various techniques and testing conditions produces an inability for industry to have consistent quality parameters across different manufactures and prevents customers from making useful comparisons regarding product quality. The intended outcome is to establish a standardized procedure with implementation guidelines that can be adopted by manufacturers and customers to monitor product quality and predict product performance.
