There are many kinds of rubber additives, and their functions are more complicated. There are more than 3000 kinds of rubber additives used internationally. According to their properties, they can be classified into the following categories: vulcanizates, accelerators, activators, reinforcing fillers, plasticizers, antioxidants, colorants, latex auxiliaries and other special purpose auxiliaries. The vulcanization process mainly uses the double bond in rubber to carry on the cross-linking reaction, in which the rubber free radicals produced by the dehydrogenation of rubber hydrocarbons can directly combine with each other and cross-link, and can also cross-link through sulfur or other non-sulfur compounds. Therefore, there are three types of cross-linking: carbon atom direct cross-linking, sulfur cross-linking and non-sulfur curing agent cross-linking.
