Vulcanization

Vulcanization is the final, and neccessary, process in manufacturing all rubber products.

Vulcanization is the curing of rubber and in this process the individual rubber molecules are cross-linked into a three-dimentional network, thereby giving the rubber product all its caracteristic properties such as elasticity and abrasion resistance.

The vulcanisation involves a chemical reaction between the rubber molecules and vulcanizing agents, which needs heat to start  ( around 150 - 250 C ) and also pressure to assure a nice, smooth surface finish.

Vulcanization can be made either static, in a press or an autoclave (for example Viking suits) , or continously in a so called Rotocure (for example Trellchem materials).

Charles Nelson Goodyear was the one discovering the vulcanization process of rubber in the year 1839.
