The effect of palm oil fatty acid additive (POFA) on curing characteristics, mechanical and morphological properties of silica filled natural rubber (NR)/ recycle rubber powder (RRP) blends were studied. Results indicate that the presence of POFA is not only improved the cure rate of NR/RRP blends but also improved it's processability. Compared to control NR/RRP blends, the presence of POFA increased the mechanical properties such as tensile strength, tensile modulus and hardness of silica filled NR/RRP blends. The presence of POFA enhanced crosslink density and improved filler dispersion of silica filled NR/ RRP blends which consequently increases the silica-NR/RRP interaction.
