Abstract: In one aspect, a foamable composition is disclosed, which comprises a base polymer, talc and a citrate compound blended with the base polymer. In some embodiments, the concentration of the talc in the composition is in a range of about 0.05% to about 25% by weight, e.g., in a range of about 2% to about 20%, or in a range of about 3% to about 15%, or in a range of about 5% to about 10%. Further, the concentration of the citrate compound in the composition can be, for example, in a range of about 0.05% to about 3% by weight, or in a range of about 0.02% to about 0.9% by weight, or in a range of about 0.03% to about 0.8% by weight, or in a range of about 0.04% to about 0.7% by weight, or in a range of about 0.05% to about 0.6% by weight.

Abstract: A communications cable is described. The communications cable can include a cable jacket, a separator structure that defines one or more channels for receiving at least one communications medium, and an insulator that surrounds the communications medium. The cable jacket can include one or more corrugations on at least one of its interior or exterior surfaces. The separator can also include one or more grooves on at least a portion of its surface. The insulator can also include one or more indentations on at least one of its interior or exterior surfaces. The corrugations, grooves, and indentations can extend along the longitudinal length of the cable and define one or more air channels for forwarding and circulating air through or on the surface the cable. The circulation of air in the cable can reduce the temperature of the cable and increase the quality of the signal transmitted through the cable.
