White fly ash filled natural rubber compounds: effect on Mooney scorch time, swelling behavior, hardness and resilience.

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 4575 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.
