A vulcanisation process is used to improve the physical properties of natural rubber. This process consists of heating a mixture of raw rubber with sulphur and an appropriate additive at a temperature range between 373 K to 415 k. Sulphur forms cross links at the reactive sites of double bonds during vulcanization, stiffening the rubber.
