A proprietary process aid that is effective at improving the dispersion of pigments, flame retardants, and fillers. XpresS-141 modifies the processing characteristics of polyvinyl chloride. It has been shown to be particularly effective at speeding the fusion time of PVC compounds. The increase in the fusion time and fusion torque can result in improved dispersion of fillers and colorants.
XpresS-141 can also be used as a processing aid for styrenic polymers, such as ABS or HIPS. When used with color concentrates or as part of the color concentrate, XpresS-141 can provide benefits such as improved cycle times and/or improved color dispersion.
