Experimental investigation on erosion resistance and hydrophobicity of silicone rubber nanocomposite

The aim of this study is to promote the development of a new functional polymer nanocomposite for application to outdoor polymer insulator. This paper deals with effects of addition of nano-scale silica filler on erosion and tracking resistance, arcing resistance, flame resistance, hydrophobicity, mechanical and electrical property of silicone rubber. As a result, it was elucidated that the addition of small amount of nano-silica filler is able to increase erosion and tracking resistance, arcing resistance, and flame resistance.
