Статья. - Journal of Metals, Materials and Minerals. - 2002. - Vol.12 No.1. - 51-57 p.This research extensively investigated the effects of particle size and amount of two types of fillers, namely, carbon black and calcium carbonate, on the curing characteristics and dynamic mechanical properties of vulcanized natural rubber. The experimental results indicated that, as the particle size of the carbon black decreased, the Mooney viscosity was increased effectively and the cure and scorch times were shortened. The same effect was obtained when the amount of fillers was increased.
