An excellent combination of ESCR and stiffness is claimed for a new HDPE for blow molding personal-care and detergent containers and toys.

An excellent combination of ESCR and stiffness is claimed for a new HDPE for blow molding personal-care and detergent containers and toys. Available from Basell Polyolefins, a LyondellBasell company, Wilmington, Del., Hostalen ACP 5231D (0.952 g/cc density, 0.30 MFR) is said to provide ESCR up to three times higher than a typical HDPE with the same density. The resin is produced in Europe using the company’s proprietary Hostalen Advanced Cascade Process (ACP), and is available for export. Normally, as HDPE density increases, the ESCR decreases. But Hostalen ACP technology reportedly can tailor the molecular-weight distribution to achieve an ESCR much higher than that of a standard unimodal grade of the same density. The resin’s high ESCR has been demonstrated to allow converters to reduce wall thickness. (302) 683-8000 • www.lyondellbasell.com
