Abstract
Prevulcanised natural rubber latex (PvNRL)/banana stem powder (BSP) composite films were prepared by adding various amounts of 10%BSP dispersion. The properties of the resulting prevulcanised (PvNRL)/BSP composite films were compared with those films containing the same amounts of calcium carbonate (CaCO3). The PvNRL/BSP composite films have higher swelling index but lower tensile properties compared to the films containing CaCO3. However, PvNRL/BSP composites films containing more than 10 parts per hundred rubber BSP showed higher moduli (M100 and M300). The PvNRL/BSP composite films exhibited the ‘knotty’ tearing behaviour, which resulted in much higher tear strength compared to those films containing CaCO3.
