Rice hull, which is one of the agricultural wastes in Japan, is required to be reused from a viewpoint of the recycling. The rice-hull silica carbon (RHSC) powder is prepared by mixing the rice hull particles with a phenol resin, and then carbonizing in nitrogen gas atmosphere at high temperatures. One of the effective utilization of the RHSC powder is as a filler for plastics and rubbers to improve the mechanical strength and the electrical conductivity. In this study, the improvement of bending strength of the RHSC/Polyphenylenesulfide (PPS) composites and electric conductivity of the RHSC/Etylene propylene diene methylene linkage (EPDM) composites were investigated by kneading the RHSC powder with PPS and EPDM, respectively. The bending strength was slightly improved and the conductivity was gradually improved with the amount of the RHSC powder. Especially, the dependence of the conductivity on the amount of the RHSC powder is utilizable for the production of antistatic polymers and rubbers.
