The extrusion of rubber compounds is often a multistep process including mixing, milling, extrusion and curing. This adds complexity to the job of a formulator trying to optimize formulations and processing conditions. Large scale process changes can first be replicated on a laboratory-scale to do so in a timely and cost-effective way. This webinar explores the effect of intermeshing and tangential lab scale mixers on the evaluation and properties of rubber formulations. We will then demonstrate how to fine tune rubber processing parameters and carbon black fill rates on the lab scale. ASTM D2230 will be used to assess processability.
