    Vulcanization of rubber by sulfur alone is an extremely slow process and can take several hours at elevated temperature (140°C or more). This is problematic becasue long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in poor mechanical properties. It is also not very economical.

    Dr. Dmitri Kopeliovich Vulcanization of rubber is a process of improvement of the rubber elasticity and strength by heating it in the presence of sulfur, which results in three-dimensional cross-linking of the chain rubber molecules (polyisoprene) bonded to each other by sulfur atoms. There are two general types of rubber: Natural rubber is produced from latex milky emulsion drawn from the

    Abstract. Although the improvement in the properties of natural rubber (NR) brought about by vulcanization with sulfur was discovered by Goodyear and by Hancock 130 years ago and the process has since become the basis of a world-wide commercial manufacturing industry, a scientific understanding of the changes taking place has begun to emerge only in the last 30 years.

    Vulcanization refers to a specific curing process of rubber involving high heat and the addition of sulfur. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms. The end result is that the springy rubber molecules become cross-linked to a greater or lesser extent. This makes the bulk material harder, much more
