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.
