The thermal conductivity and diffusivity of a series of three-phase styrene butadiene composites were investigated using the transient plane source (TPS) technique. Both of the series contained a variable amount of natural rubber, as well as variable amounts of silica and clay. The thermal properties decreased sharply at 10 phr filling, but increased subsequently after that. It was determined that silica resulted in better (higher) thermal properties as compared to clay....
