A process called reverse vulcanisation allows sulphur to be used to make a stable polymer, an alternative to carbon plastic. The process requires the sulphur to be reacted with organic crosslinker molecules to make it stable and this process can require costly high temperatures and long reactions times, whilst also creating harmful by-products.

Elemental sulfur is purchased on the international market having been recovered as a by-product of the oil refining process. This sulfur is melted by steam coils at 140°C in brick lined tanks. The molten sulfur is filtered to remove any impurities (usually iron or organic compounds). Lime is added to reduce the acidity of the molten sulfur

Sulphur vulcanization takes place in three stages. (1) Induction period. The curatives react with themselves in preparation for the cross-linking reaction. This period allows the ingredients to be safely mixed avoiding premature curing ('scorch'). (2) Vulcanization of the rubber. Sulphur bridges between rubber chains are actually produced. (3)

The oxidation of sulphur dioxide to sulphur xide is a reversible process. The pressure is maintained at 1.2-1.5 atm and temperature at 410-430°C. If the temperature rises above 430°C then the equilibrium is displaced away from Sulphur xide, hence it is very important that operating temperature should be maintained in this range.
