The Effect Of Nanosilica Filler On Curing Characteristics, Mechanical And Morphological Properties Of Standard Cambodian Natural Rubber Nanocomposites

Nanosilica (NS) and maerogel, which are mesoporous light solid materials, low bulk density, low thermal conductivity, and high surface area with microstructure network consists of nano sized pore. NS was used as filler in Standard Cambodian Rubber (SCRL) nanocomposites. 3 phr of NS filler showed...
