WebAug 22, 2024 · Silicone rubber composite insulators are subjected to various environmental stresses. More and more faults occur when composite insulators operate for more years. For instance, the entire power system is significantly impacted by the decay-like fracture of the composite insulator [ 6 ]. Webvarying weight percents of simple nonionic hydrophilic groups have been synthesized and characterized by FTIR and 13C-NMR. Emulsions have been made by self-emulsification of those polymers in pure water and also by emulsifying silicone oil using those polymers as oil-in-water type emulsifiers. The stability of those emulsions have been examined
