LyondellBasell announced recently that its breakthrough Hostalen Advanced Cascade Process (Hostalen ACP) technology is now available for license to third parties. The technology's enhanced multi-modality enables the production of high-performance HDPE resins used in demanding film, blow molding and pipe applications. A key feature of the Hostalen ACP slurry process is the multi-staged reactor cascade, which uses Ziegler catalysts (Avant Z-501 and Avant Z-509 catalysts) that tailor the multi-modal molecular weight distribution specifically required for each HDPE grade.
According to the company, the multi-modal Hostalen ACP technology addresses customer needs that are beyond the limits of standard bi-modal HDPE, producing resins with an advanced toughness/stiffness balance, superior impact resistance, higher stress crack resistance and significantly improved processing advantages. LyondellBasell produces over one million tonnes per year of Hostalen ACP resins at the following wholly-owned and joint venture locations:
