...s both in manufacturing processes and existing PE100 grades. One focus of development work was the reduction of sagging at large pipe diameters and high wall thicknesses. Improved PE100 grades, such as multimodal Hostalen pipe grades by the ACP process now allow the production of large, thick-walled pipes with a uniform wall-thickness distribution. New pipe concepts with multilayer structure, or so-called functional layers have also helped to expand PE-HD’s position. Pipes with special protectiv...

...the modification of individual parameters within the existing cascade polymerisation process and, without necessitating any changes to the basic processing sequence, in the development of a new process, the “Advanced Cascade Process – ACP”, in which specific partial processes take place in reactors arranged in tandem (Fig. 5), the resultant product being a multimodal PE-HD [5]. This cascade process permits incorporation of the important, property-influencing co-monomers in the high-molecular fra...

... CAE simulations (computer-aided engineering) gives OEMs the ability to use this Lupolen together with other Lupolen grades as a long-lasting material – without compromises in machine throughput or weldability. The PE-HD grade Hostalen ACP 6031D is a material with 10 % greater environmental stress crack resistance (ESCR) and high stiffness. This allows manufacturers of extrusion blow molded bottles and containers of household chemicals, for instance, to save on material. These properties are ach...

...only available) are expected shortly. Packaging, Film and Blow Molding There are also certain segments in the packaging sector where the use of particularly high quality PE-HD grades is sensible. In closure cap applications Basell’s Hostalen ACP 6541 A has been able to replace its competitors in particular because of its better mechanical properties such as better stress cracking resistance and stiffness (Fig. 2). Multi-modal polyolefins that are now being offered by some European manufacturer...

...ey possess, among others characteristics, an optimized molecular weight distribution; the stiffness and impact strength at low temperatures benefit here. In-situ Blends Combine Requested Characteristics The new Hostalen Advanced Cascade Process (ACP) from LyondellBasell achieves similar results with PE-HD (Fig. 2). The basis for the new technology is the Hostalen Suspensions Process; the polymerization reaction takes place in several reactors in succession. Each reactor can be ch...

...ion. With this so-called reactor blend or in-situ blend, the processing and application properties can be much better optimized than by subsequent mixing of different polymers. Bi- or multimodal PE-HD is produced by the advanced cascade process (ACP) developed by LyondellBasell. With this processing technique, polymerization is distributed between several reactors connected in series. Consequently, important comonomers can be incorporated more selectively and effectively into the high-mo...

Products with Multimodal Molecular Weight Distribution The Hostalen Advanced Cascade Process (ACP) to produce PE-HD products with a multimodal molecular weight distribution was developed by LyondellBasell Industries to overcome this intrinsic conflict. PE-HD products with a multimodal weight distribution consist of at least three different poly...
