However many plastics have very putrid odors when burning so it's hard to tell just from the fumes. But vulcanized rubber will not melt. Anything that melts and drips when held in a flame is most likely PVC of one sort or another. If fillers like carbon black or other materials were added to the PVC then the material may not catch fire at all, or on the other hand, may burn even more easily than "pure" PVC.
