This is actually what I do for a living. I definitely agree UHMW is probably your best tape for this particular application- it will not wear as easily, not quite as low coefficient of friction but should be good enough, and it will be either an acrylic or rubber adhesive which is better in case you have to take it off. PTFE tapes are commonly silicone since they are used for their stability at relatively high temps, although they do come in acrylic or rubber.Silicone would make it a pain if you did have to take it off and try to stick anything else where you had the tape previously. UHMW can be milky white to clear.
