Silica based bagasse ash (BA) from bio-mass power plant station in Nakhonsawan, Lopburi and Suphanburi provinces of Thailand were used and incorporated into natural rubber (NR) at 0, 15, 30 and 45 parts per hundred rubber (phr) of silica contents and the cure and mechanical properties were assessed and compared. The majority of all bagasse ash powder had particle size of less than 150 micrometer. The cure characteristics of bagasse ash/natural rubber (BA/NR) composites had no effect on scorch time and cure time. The overall mechanical properties (moduli and hardness) of bagasse ash/natural rubber (BA/NR) composites increased with increasing ash content, except for elongation at break which decreased with ash content. 15 phr of silica content in bagasse ash powder from Nakhonsawan province gave the optimum mechanical strength as compared with other two ash sources. The outcome of this research could be of value-added for agriculture to industry benefits in sustainable development.
