Effect of rice husk ash and hydrated silica on the dielectric properties of LDPE composites

N.Samson Maria Louis, ArjumanBanu, S.Sudha

LDPE composites of rice husk ash (RHA) and hydrated silica at different filler concentrations were prepared and the dielectric properties were investigated. The optimumhydrated silica filled composite (30 parts/100 parts of LDPE) exhibits good dielectric constant and increased dielectric loss, which leads to the application as a good insulator. LDPE filled with RHA can be used as high frequency dielectrics due to low dielectric loss, resulted by the non-polar nature of RHA.
