I know from direct experience, Spectra cord from Berkeleypoint.com does melt (it has no sheath), and Technora based core of the New England Tech Cord does not (but as you point out, the Nylon sheath does).

Take a look at this test of high tech cord and you'll see the melting point of Spectra is noted as low.
