Craig, > Martin, > PVF stands for "polyvinyl fluoride". I seem to remember that it is actually "polyvinyl carbon floride" but I'm not certain.
I'm a bit confused myself, but let me quote from Mimmo Peruffo's U.S Patent for "Nylgut" (not named as such in the patent, it is Polybutylene Terephthalat as used for musical strings). " Recently PVF (Polyvinyldenchoride), also improperly known as "carbon", has also been used to make musical strings". I haven't the vaguest idea what denchoride is, perhaps a form of flouride, but I have to assume the word is correct as it is in the patent as issued. Organic chemistry was too complicated for me fifty years ago when there were a lot less compounds. But I believe all the thermoplastics are compounds of hydrocarbons, so they all have carbon. Perhaps the denchoride is a "salt" of carbon and flouride (my old chemistry book is a bit short on that stuff, but it does show how to make the silicon floride "salt"). Whatever, some call 'em "carbon" and some call 'em PVF - but they seem to be the same thing.
