The foamable composition comprises at least one polymer and a foaming agent. The foaming agent comprises a talc or a talc derivative. The polymers described herein comprise a substantially non-halogenated polymer. One or more additives are added to render the compositions flame retardant and/or smoke suppressant. Also described are Power over Ethernet (PoE) cables, having at least one electrical conduit comprising an electrically conductive core, an insulation that at least partially surrounds said electrically conductive core and a polymeric separator extending from a proximal end to a distal end and having at least one channel adapted for receiving the at least one electrical conduit. The PoE cables are capable of carrying about 1 watt to about 200 watts of power. ## Claims ### Claim at position 1 1-88.
