As we all know, the silicone seal ring is mainly made of rubber. High temperature resistant silicone strip manufacturers tell you that rubber as an insulating board material is because rubber has incomparable excellent performance of other materials. First of all, latex rubber trees and other plant sources, high elastic rubber has become a reason to choose as an insulating rubber sheet, good elasticity, allowing insulation rubber coil floor in other processes, is not easy to break, and has good extensibility and expansibility.

Second, vulcanized rubber products processing is one of the main technological process, heating or irradiation conditions, raw rubber compounds and rubber vulcanizing machine reaction of crosslinked rubber from linear structure of large molecules become 3 d mesh polymer structure, lead to physical and mechanical properties and other properties of rubber has been obviously improved, becomes vulcanization process, as the technology and production, And the development of the high temperature vulcanizing machine is no longer a necessary condition for curing some rubber can be at lower temperatures, even in room temperature can be vulcanized drinks, some compounds available physical methods, such as the use of plastic material, gamma rays, without crosslinking curing agent and curing is defined so widely, under certain conditions, the linear network structure of rubber molecules into the process. Vulcanized rubber, some properties will change. Natural rubber, for example, with a higher level of vulcanization, mechanical properties will change. Elasticity, tensile strength, tensile strength, tear strength, hardness will increase, but elongation, compression ^ deformation, fatigue, heat will decrease; Change the physical properties, permeability, permeability to reduce insoluble, but can improve the heat resistance swelling; Chemical stability will change dramatically.

Natural rubber tells you that actually, when it comes to theory, it is the crosslinking reaction that makes the presence of high group or atomic chemical activity difficult for aging reactions. The network structure obstructs the diffusion of low molecular weight, which leads to the difficulty in popularizing rubber aging caused by free radicals.
