Abstract: Blends of natural rubber (NR) and synthetic rubbers are widely used in the rubber industry to meet specific performance requirements. Further, the emerging field of organomodified clay/rubber nanocomposites could provide a host of novelmaterials having a unique combination of properties to meet various stringent service conditions. Previous studies have shown that at very low dosages, china clay (kaolin) modified with sodium salt of rubber seed oil (SRSO) improved the cure characteristics and physico-mechanical properties of NR. Results of the present study show improved cure characteristics and physico-mechanical properties for blends of NR with butadiene rubber and nitrile rubber containing 4 phr of SRSO-modified kaolin as indicated by reduction in optimum cure time along with higher tensile strength, tensile modulus and elongation at break for their vulcanizates as compared to those containing unmodified kaolin. The SRSO-modified kaolin/rubber nanocomposites showed improved flex resistance, reduced heat build-up, tan delta and loss modulus and higher chemical crosslink density index, indicating a reinforcing effect of the SRSO-modified kaolin, enabling the nanocomposites to have potential industrial applications.
