Union Carbide, before acquired by DOW, had a significant business of Polyolefins Wire and Cable Compounds. DOW, with its Inspire technology using Metallocene catalysts is now developing PE grades to enhance processability, extrudability and uniformity of cell structure of PE foam cables. The higher mechanical properties of Inspire PE polymers would also allow cable manufacturers to reduce thickness of coating. DOW, after initial introduction of HDPE power cable compounds at the recent Wire 2002 conference, plans to introduce more grades to achieve higher temperture resistance, higher insulation properties that will yield improved electrical performance.
