<p>Cable insulation shields comprising, in weight percent based upon the weight of the insulation shield, (A) 37-53% of ethylene vinyl acetate (EVA) having 30-33 wt% of units derived from vinyl acetate, (B) 10% or more nitrile butadiene rubber (NBR) having 25 to 55 wt% of units derived from acrylonitrile, and (C) 35% or more carbon black having (1) 80-115 milliliters per 100 grams (ml/l00g) dibutyl phthalate (DBP) absorption value, (2) 30 to 60 milligrams per gram (mg/g) iodine absorption (I2NO, and (3) 0.3 to 0.6 grams per milliliter (g/ml) apparent density), exhibit a strip force against an adjacent crosslinked polyethylene insulating layer of less than 5.4 kN/m (15 pounds per one-half inch).</p> |
