ABSTRACT:
Disclosed are materials used to fill electrical and light waveguide transmitting communications cables to make them waterproof. The filling materials have superior waterproofing, dielectric and handling characteristics and are made from compounds of styrene-ethylene-butylene-styrene, styrene-butadiene-styrene or styrene-isoprene-styrene type block copolymers dissolved in paraffinic or naphthenic type mineral oils with a minimal content of aromatic hydrocarbons, inorganic hollow microspheres and, if desired, an additive such as low molecular weight polyethylene or glycerol hydroxy stearate.
