Application data is presented for the newly developed additive formulations designed for their use as flow and release property enhancers for polyolefins. Significant performance improvements in HDPE, PP /TPO polymers have been obtained at low loadings (0.3-0.5%) of the newly developed process aid additives. Rheological data for these additives is supported with the development of an effective technique for quantifying ejection force measurements. One of the key additive formulations MoldWiz~R XP-l-35 CPD has also been found to be an excellent scratch resistance additive in TPO when used at 2% loading.
