What is Vulcanisation?
Vulcanisation is the irreversible process of curing elastomers. Originally, vulcanisation referred exclusively to the treatment of natural rubber with sulphur but has grown to include the treatment of synthetic rubbers with other curatives (such as peroxide and metal oxides). During vulcanisation, cross-links are formed between the polymer chains within the rubber, resulting in improved elastic properties over a greater temperature range. To read more about the formation of cross-links, read our article on Curing and Crosslinks.
