Rubber is a substance. Natural rubber is formed of elastic hydrocarbon polymers, which are almost exclusively made up of isoprene (a hydrocarbon diene monomer). Synthetic rubber is also a polymer, but also contains monomeric units from different chemical families. Regardless of the make up of the monomers, the polymer is technically only one molecule so it is a substance. Out of interest, if you heat up most rubber it will melt and liquify. If you then cool this rubber it will reset into the original rubber nature.
