General description

Silicone oil is a liquid based siloxane that is part of the methyl silicone fluid system. It has a viscosity of 100 cSt with a refractive index of ~ 1.402 and a dielectric strength of ~ 14 kV/mm. It′s surface tension tends to increase with an increase in the viscosity.[1]

Application

Silicone oil can be used for a variety of application such as: development of magnetorheological elastomer for force sensors[2][3], a cosmetic additive[4], a dielectric coolant[1], a lubricant and antiflatulent agent.[1]
