By using a semi-efficient sulfur accelerated vulcanization system, a research about the effect of the alcanolamide on cure characteristics and hardnes propertiess of natural rubber filled silika and alkanolamide been done. Alcanolamide produced from palm oil derivatives reacted with dietanolamine. Alcanolamide aaded into rubber with levels 1.0, 3.0; 5.0; 7.0; 9.0; phr. It was found that alcanolamide gave shorter Scorch time and cure time. Alkanolamide also exhibited higher torque different, tensile moduli, tensile strength, and crosslink density up to 5.0 phr and ten decrease with future increaseing addition of alcanolamide.
