Thermo-mechanical behaviour of rubber materials during ...

Since the state of vulcanization (curing) can be predicted during the heating process, adjustment of the heating parameters is possible in order to optimize the curing process and the tolerances of the final shape of the rubber sealings. During the vulcanization process chemical and electrochemical reactions can occur.

Rubber Vulcanizing Capabilities - Rubber Vulcanization ...

Curing, also known as vulcanization, causes the long polymer chains that rubber is composed of to become crosslinked. This prevents the chains from moving independently, allowing the material to stretch under stress and then return to its original shape when the stress is released. The different curing methods available involve heating the ...

Joe Walter considers how the tire curing and vulcanization ...

The curing process producing rubber-sulfur cross-linking was subsequently dubbed vulcanization after Vulcan, the mythological god of fire. However, the original procedure, discovered by Charles Goodyear in 1839 (see Tire Legends, July 2016, p46), was time-consuming and tedious – often requiring the application of heat for four or more hours.

A New Method to Predict Optimum Cure Time of Rubber ...

The degree of vulcanization of a rubber compound has a big influence on the properties of the final product. Therefore, precisely defining the curing process including optimum cure time is important to ensure the production of final products having high performance. Typically, vulcanization is represented using vulcanization curves.
