Cable filler compositions comprising a mixture of (a) styrene block copolymer, (b) crystalline polypropylene copolymer and (c) mineral oil

摘要

A cable filler composition comprises a mixture of mineral oil, a styrene-ethylene butylene-stryene block copolymer, and about 2-6 percent by weight of a thermoplastic polymer comprising an isotactic, crystalline polypropylene copolymer containing 0.1-4% by weight of an olefinic comonomer, the copolymer having a molecular weight of between 20, 000 and 40,000.
