The shelf-life of natural rubber latex products are highly dependent on various environmental factors. To improve the quality as well as performance, fine particle dispersons are employed in their formulations. The degradation behaviour of silica (SiO2) and Titania (TiO2) nanoparticles incorporated natural rubber latex (NR) nanocomposites against various degrading agents viz, thermal, gamma-radiation, UV radiation and chlorination were studied. The properties such as tensile strength, elongation at break and modulus were recorded after exposing the latex films to various degrading environments. Compared to the gum vulcanizates, addition of nano SiO2 and nano TiO2 improved the tensile strength even after ageing. Enhanced UV resistant properties were noticed for nano titania latex composites from mechanical property measurements. Nano SiO2 (0.3 phr) imparted maximum tensile strength after chlorination.
