Salmah C.M. Ruzaidi and A.G. Supri School of Material Engineering Universiti Malaysia Perlis UniMAP 02600 Jejawi Perlis Malaysia Corresponding author irsalmah@unimap.edu.my Abstract The tensile properties and morphology of polypropylene PP ethylene propylene diene terpolymer EPDM Kaolin composites were investigated. Maleic anhydride-grafted-polypropylene MAPP was used as a compatibiliser to improve the compatibility of kaolin filled PP EPDM composites. Results show that incorporation of MAPP increased the tensile strength and Young s modulus but reduced the elongation at break. Scanning electron microscopy SEM of the tensile fracture surfaces of composites indicates that the MAPP improved the interfacial interaction between kaolin and PP EPDM matrix. Keywords polypropylene ethylene propylene diene terpolymer kaolin compatibiliser composites 1. INTRODUCTION The incorporation of mineral fillers into thermoplastics elastomers has been widely practiced in industry to extend the elastomers and to enhance certain properties. Fillers often increase the performance of polymeric products. The degree of improvement depends on the choice of filler origin particle size and shape the fraction of filler and the surface treatment promoting interaction between the polymer matrix and filler.1 The addition of fillers to polymers is a fast and cheap method to modify the properties of the base materials. For this reason particulate filled polymers have been and continue to be the subject of increasing interest in both industry and research. In this way strength stiffness electrical and thermal conductivity hardness and dimensional stability among other properties can be tailored to the required values.2 The addition of filler to polyolefins seeks to reduce production costs with subsequent
