        You can use  a technique which I pioneered and refer to
        (in full professional modesty, of course) as Michael's
        Test.  It amounts to pyrolytic olefactory analysis.  In
        other words you burn it, and then sniff it.

        You must obtain some genuine Polythermaleze resin, or else
        a wire specimen coated with same.

        Heat the resin (or wire) in a suitably scientific fashion
        (a match, or butane lighter) until it combusts or smokes.
        If it ignites, blow out the flame.

        Now - the most important part.  Smell the smoke.  Memorize
        that aroma!

        Next, repeat the test on your unknown.   If they smell the
        same, they are the same.  (Michael's Rule of Polymer

        This test works quite well on virtually all polymers --
        certainly on all polymer classes.  It cannot easily distinguish
        between homologs  (polyethylene and polypropylene,for instance),
        but it easily identifies Nylon, polyesters, polyalkylenes,
        polyurethanes, polyimides, Bakelite/phenolics, acrylics, ABS,
        natural rubber, polystyrene, etc.
