Characterization and properties of calcium carbonate filled polypropylene (PP) / ethylene propylene diene terpolymer (EPDM) composites

Composites of thermoplastic elastomer blend of polypropylene (PP) and ethylene propylene diene terpolymer (EPDM) reinforced calcium carbonate (CaCO3) was investigated. All the composites were prepared by using Z-blade mixer at 180oC and rotor speed 50 rpm. The effect of filler loading of calcium...
