Effect of the Characteristics of Maleic Anhydride-Grafted Polypropylene (MAPP) Compatibilizer on the Properties of Highly Filled (85%) Kenaf-Polypropylene Composites

Kenaf polypropylene composites with high fiber load of 85 wt% were produced using glycerine as a processing aid and maleic anhydride-grafted (MAPP) compatibilizer/coupling agent. Commercially available MAPPs different molecular weights anhydride contents used to determine what properties the important achieve mechanical these highly filled composites. A homo-polymer random-polymer, compared matrix polymers. Composites high-shear kinetic mixer followed by compression molding at pressures ranging between 345 5520 kPa. The data suggests that adding low weight content concentrations 5 resulted in highest properties. authors suggest combination surface area, viscosity MAPP are resulting good stress transfer fibers polymer.
