Rheometer and mathematic analysis method effectively evaluate silica filler dispersion in rubber matrix for optimum filler loading level.
Abstract
The feasibility of using rheometer and mathematic analysis method to evaluate the dispersion of filler in rubber matrix and achieve an optimum filler loading level were verified by RPA,SEM and TEM analysis.The results showed that the three methods of RPA,SEM and TEM,as well as rheometer and mathematic analysis method came to the same result that the optimum addition level of silica filler in STU/silica/NR compound with 0.92 phr STU was about 30 phr.It was suggested that the rheometer and mathematic analysis method could be effective for evaluating the dispersion of filler and optimum filler content in designing rubber composite.
