Abstract

By using a semi-efficient sulphur accelerated vulcanization system, an investigation of the effect of  alkanolamide on cure characteristics and hardness  properties of kaolin-filled natural rubber compounds was carried out. Alkanolamide was synthesized  from Refined Bleached Deodorized Palm Stearin (RBDPS) and diethanolamine. Alkanolamide was incorporated into the kaolin filled-natural rubber compound at 1.0; 3.0; 5.0 and 7.0 Parts per-Hundred RubbeR (phr). It was found that alkanolamide gave shorter scorch time and cure time. Alkanolamide also exhibited higher torque different,  crosslink density, and hardnessup to 5.0 phr and then decreased with further increasing the loading of alkanolamide.
