During vulcanization, active functional groups or double bonds in the macromolecular structure of the rubber are gradually reduced due to cross-linking, thereby increasing chemical stability. On the other hand, due to the formation of a network structure, the movement of rubber macromolecular segments is weakened, and the diffusion of low-molecular substances is severely hindered. As a result, the stability of the action of rubber on chemicals is improved.
Although rubber has many excellent properties, there are still many shortcomings in the raw rubber itself, and the use of raw rubber alone cannot produce rubber products that meet various requirements for use. All kinds of rubber must be added with the appropriate amount of related additives in order to make practical rubber products. In addition to the technical requirements, the performance of the rubber can be improved after adding the compounding agent, so that it can meet the corresponding use requirements and reduce the cost of rubber products.
