Abstract

In this work, the influence of particle size and concentration of fillers used in silicone rubber compounds for outdoor insulation is investigated. Alumina tri-hydrate and silica with mean particle sizes of 5 and 10 μm are used as fillers with concentrations of 10, 30 and 50% by weight in a two-part room temperature vulcanized silicone rubber base polymer. The results from inclined plane tests show that samples with high concentrations of filler and/or smaller particle size have better tracking and erosion resistance than samples with lower concentration and/or larger particle size.
