The addition of carbon black to an elastomer can have a positive effect upon its mechanical, electrical and physical properties. Therefore, QC and process labs need to determine the exact concentration of carbon to ensure product quality and monitor production costs. A rapid determination of the carbon black content allows quick feedback to production and for adjustment when required. A standard approach to this analysis is ASTM D1603, which provides gravimetrical determination of carbon black content following a lengthy pyrolysis step under nitrogen.
The UltraFAST crucibles allow the PYRO user to dramatically reduce the overall ashing time, from start to end thanks to their innovative material that allows the samples to be surrounded by a constant airflow. They are made of an innovative material that, although chemically and thermally resistant, allows the samples to be surrounded by a constant airflow which, in turn, accelerates the ashing process. The ashing time is therefore reduced.
