Abstract

Abstract A cable fill composition comprises a paraffinic or naphthenic oil, a styrene-ethylene butylene-styrene block copolymer, and a linear polyethylene wax having a molecular weight of about 1000, whereby an improved drip point of the composition is obtained. The composition is suitable for filling voids in electrical and light-conducting cables.
