...ntially, which is especially advantageous when processing temperature-sensitive materials. Material Degradation within Limits The mild treatment of the material in the ring extruder was demonstrated when processing a standard polypropylene (grade: Vestolen 17M10, manufacturer: DSM Polyolefine GmbH, Gelsenkirchen). The operating parameters of a co-rotating twin-screw extruder belonging to the polypropylene manufacturer was used for comparative data. The process section of the ring extruder had ...

...tice The graphs in Fig.7 plot the calculated against the measured energy. Generally speaking, good correlation was achieved for all materials. Deviations occurred primarily at low outputs coupled with high speeds. These were most noticeable with Vestolen P7000 and PE-LLD. At the above-mentioned operating points, there was high dissipation, so that the interfacial temperature between the melt and barrel wall differed significantly from the actual barrel wall temperature. This interfacial temperat...

...ariable range, and was therefore held constant. Thin sections were taken from these panels along the flow path and the outer layer thicknesses measured by polarisation microscopy. A typical layer structure of an injection-moulded panel of PP (grade: Vestolen P 7000, manufactured by: DSM Petrochemicals) is shown in Fig. 5; also see [10, 11]. The measured outer layer thicknesses are shown in Fig. 6. The results show that, - a) at constant injection time and increasing melt temperature, and - b) at...

It became the second largest European producer with more than 1.5 million tonnes capacity, just behind then European leader Montell (Himont-Shell JV). DSM took over Vestolen GmbH early 1998 and Dow started mid 1998 its first European PP production unit, located in Schkopau. A few months later, Borealis and PCD joint forces. A new wave of restructuring started early in the new millennium. Basell was formed in Oct...

PE: Pipes and Grass At the K show, Sabic introduced the Vestolen A 6060 R polyethylene, which is designed for water ducts and is being applied in Montenegro. Borsafe is the name of a Borealis product designed to manufacture pipes of high qualities and stiffnesses, serving the same purpose. Both of these systems are PE...

For over 30 years, hot and cold water installations have used pipes made from random polypropylene copolymers (PP-R) due to their good resistance to heat and pressure; examples of standard materials here are Vestolen P9421 (Sabic) and Borealis RA130. The new PP-RCT class of materials enables pipes to be used at higher pressures or their wall thickness to be reduced. The polymer beta PP-R RA7050 (Borealis) is tailormade in terms of molecular weight distribution a...
