ABSTRACT:
A semi-foamed polyethylene tape for use in the molding of foamed jacket pethylene cables. After tumble mixing low density foaming polyethylene, ethylene vinyl acetate co-polymer and polyethylene color concentrate, the tape is extruded on a thermoplastic extruder having a maddox mixing screw that effectively mixes polyethylene compounds and a slot die with a suitable opening dimension. The tape is then quenched. By controlling manufacturing variables the tape is foamed to 40% to 50% of its maximum. The tape is then foamed to 100% maximum during the manufacturing of a cable assembly.
