Using its patented bimodal PE process technology, Borealis A/S (HQ: DK-2800 Lyngby – Germany: Borealis Deutschland GmbH, Am Bonneshof 6, D-40474 Düsseldorf) has now developed two more new grades and put them on to the market. The first grade, ME6597, has a density of 931 kg/m³ and is equally suitable for LDPE and LLDPE film manufacturers, while the second, HE 6995, with a density of 946 kg/m³, should, the company says, be processed by HDPE extrusion to obtain optimum results. Like LE 6592 (density: 923 kg/m³), which was successfully introduced about two years ago, these two new products – so the press was told – had the advantage of reduced thickness, easy processing, a higher yield stress and higher rigidity.

Borealis has been operating a 140,000 t/y plant in Finland, producing LDPE, MDPE and HDPE with the Borstar technology, since 1995. With this process, PE can be manufactured with bimodal (broad) molar mass distribution even in the low density range. Apart from this, it can be used to tailor the materials and thus the product properties for a particular application.
