Natural rubber (NR) latex-organokaolin compounds have been investigated. The intercalated kaolin (100% CEC-CTAB of clay) was used in aqueous rubber latex dispersion, from which a coagulum was obtained. The coagulum was used in natural rubber compounds and evaluated for its cure: scorch; ts1, optimum cure; t90 min, minimum (ML) and maximum (MH) torque and mechano-physical properties viz: M100, M300, EB (%), hardness and abrasion in mg/1000 rev. The scorch and optimum cure indicated a progressive drop with addition of organokaolin in natural rubber latex based compounds. Vulcanisate mechanical properties generally showed increase as organokaolin loading increased. A correlation between the measure of extent of vulcanization (MH-ML) and properties such as tensile strength, elongation at break, abrasion and hardness showed that the extent of crosslinking as a result of rubber-filler interaction of the natural rubber based compounds increased as organokaolin loading increased.
