The effects white fly ash (WFA) filled natural rubber compounds on mooney scorch time, swelling behavior, hardness and resilience of natural rubber compounds were investigated in the range 0 to 30 phr. The size of WFA that was used in this study was 45-75 µm. The result indicated that Mooney scorch time of natural rubber compounds was decreased with the increasing of temperature. The increasing of WFA loading gave natural rubber compounds a better resistance towards swelling whereas crosslink density and hardness showed an increasing trend. However, the resilience of natural rubber compounds exhibit a decreasing trend.
