Looked like teflon to me. Here is the real answer "Plenum cable is jacketed with a fire-retardant <https://en.wikipedia.org/wiki/Fire_retardant> plastic jacket of either a low-smoke polyvinyl chloride <https://en.wikipedia.org/wiki/Polyvinyl_chloride> (PVC) or a fluorinated ethylene polymer (FEP <https://en.wikipedia.org/wiki/Fluorinated_ethylene_propylene>). Polyolefin <https://en.wikipedia.org/wiki/Polyolefin> formulations,"
It is NOT designed to resist heat. There is no requirement that it not melt The requirement is that it not produce great amounts of toxic smoke when it does burn. In practice it is harder and shinier looking than normal patch cable I would think that the old fashion telephone handset cable might work too. Both types have RJ style connectors so the cable could be replaced in seconds and they are cheap enough so you could keep a supply of spares and change them out before they fail. The shielded type are not the best in terms of flexibility. The shielding is done with metabolized foil. The FIRST CLASS solution is a wireless link. It only needs to go about a foot so could be low power enough to run off a coin battery for a long time. Either radio or optical The IR system used in TV removes work well for short distances.
