Abstract
The effect of filler loading on tensile strength force at break modulus stress-strain relationship and surface morphology of natural rubber latex (NRL) films was studied. Grounded calcium carbonate (GCC) loaded into NRL latex compounds and the results obtained from latex films formed from these compounds showed that their tensile strength and force at break improved initially but leveled and dropped when the GCC loading is more than 5 in NRL films. Disturbing the filler arrangement in the rubber matrix by scragging the test piece of filled NRL films changed the elastic constant value (C1) of the filled test pieces with a large difference in highly filled films. Expected agglomeration of filler in gloves visualised via the microscopy technique indicated disinclination of GCC to distribute well in NRL films. The discrepancy seen in SEM micrographs between differently filled films could be related to surface roughness of the NRL films. Among filled NRL films the one containing 20 of GCC had the smoothest appearance in its surface morphology. Micrographs from FIB-SEM techniques show clear clustering of fillers at high dosages in the NRL films.
