Abstract
This study was carried out to develop statistical models of formulation parameters for physical and mechanical properties of natural rubber/starch composites using a 22 full factorial central composite design via a response surface methodology. It was to measure the significance and interaction of two identified formulation variables, namely, carbon black (X1) as the filler and glycerol (X2) as the processing oil. The factors are optimized to achieve maximum cure characteristics, rebound resilience and tensile strength. The composites were prepared by melt compounding process using a Haake internal mixer at a constant temperature and rotor speed of 60 C and 60 rpm. Through the use of regression models that were developed for the quadratic model, a maximum rebound resilience of 71% and tensile strength of 22.57 MPa was obtained for a carbon black loading of 50 phr and a glycerol loading of 7%
