Difference Between Vulcanized and Unvulcanized Rubber
Difference Between Vulcanized and Unvulcanized Rubber Definition. Vulcanized Rubber: Vulcanized rubber is rubber that has undergone the process of vulcanization. Unvulcanized Rubber: Unvulcanized rubber is rubber that has not undergone the process of vulcanization. Structure of the Rubber. Vulcanized Rubber: Vulcanized rubber has an intermolecular system with highly cross-linked polymer chains.

Making Rubber Stronger: How to Vulcanize Rubber
Making Rubber Stronger Through Vulcanization Rubber is a polymer of isoprene that is formed with double bonds between each of the individual monomers (or units). In simple terms, one of these bonds is flexible and can allow the polymer to take up many shapes and sizes, which is what basically gives rubber its property of elasticity.

Composition of Vulcanizing System, Course of Vulcanization
In considering the special features of the vulcanization of SBR rubber, as one which vulcanizes comparatively slowly, it was natural to expect that the different activities of the vulcanizing systems in joined plies condition a sharp difference in the course of vulcanization, which might affect the bond strength considerably.

Natural rubber
Natural rubber is often vulcanized - a process by which the rubber is heated and sulfur, peroxide or bisphenol are added to improve resistance and elasticity and to prevent it from perishing. Carbon black is often used as an additive to rubber to improve its strength, especially in vehicle tires, which account for about 70% (~9 million tons) of carbon black production.
