The preparation of phenyl rubber involves complex organic synthesis processes, mainly through co hydrolysis or co polymerization reactions of phenyl containing cyclic siloxanes and dimethyl cyclic siloxanes. Accurate control of the phenyl content is crucial in the production process, as it directly determines the physical performance range of the final product. The polymerization reaction needs to be carried out under strict catalyst system and temperature and pressure control to ensure the uniformity of molecular weight distribution and the activity of end group structure.

After the reaction is complete, it needs to go through post-treatment processes such as removing low molecular weight volatiles and neutralizing catalysts to obtain pure raw rubber. Due to the relatively high rigidity of the phenyl rubber molecular chain, its Mooney viscosity is usually high, which poses certain challenges for subsequent mixing and processing.

In the processing and application stage, phenyl rubber usually needs to go through processes such as mixing, vulcanization, and secondary vulcanization to produce the final product. In order to improve its mechanical properties, it is usually necessary to add reinforcing fillers such as gas-phase white carbon black. Due to the unique burn resistance and self extinguishing properties of phenyl rubber, specific heat-resistant additives or structural control agents are often added in formula design to further enhance its performance in extreme environments.

In the selection of vulcanization systems, peroxide vulcanization is often used to crosslink linear molecular chains into a network structure through high temperature and high pressure. During the processing, it is necessary to strictly control the vulcanization temperature and exhaust process to prevent the formation of bubbles inside the product. In addition, for special application scenarios such as conductivity or thermal conductivity requirements, functional fillers can be added to modify phenyl rubber to expand its adaptability in complex industrial environments.
