FILLING MATERIALS FOR COMMUNICATIONS CABLE ABSTRACT OF THE DISCLOSURE Disclosed are telephone cable filling materials and telephone cables comprised of a plurality of insulated electrical conductors twisted together to form a core in which there are a multiplicity of interstices between the insulated electrical con- ductors filled with the cable filler materials. The filling materials are composed of a petrolatum base material and inorganic microspheres and can be divided into two groups: (1) a first group to fill cables used at temperatures below the melting point of the petrolatum and (2) a second group to fill cables that may be used above that temperature. The first group is composed of mixtures of 40 to 90 weight percent petrolatum and 1 to 60 weight percent inorganic hollow (air filled) microspheres. When mixtures from this group are used as a filler in a telephone cable, the filler has a drip point nearly equal to the average melting point of the petrolatum, normally 57.2°C. The second group is composed of two embodiments. The first embodiment comprises 62 to 95 weight percent petrolatum, 1 to 35 weight percent inorganic hollow micro- spheres, and 1 to 8 weight percent low molecular weight polyethylene dissolved in the petrolatum. The second embodiment comprises 60 to 98 weight percent petrolatum, 1 to 39 weight percent inorganic hollow microspheres and 1 to 15 weight percent of glycerol hydroxy stearate dissolved in the petrolatum. When mixtures from the second group are used as a filler in a telephone cable, drip points ranging from the average melting point of petrolatum to temper- atures in excess of 75°C are observed. -1-
