Effect maleic anhydride polypropylene on properties of calcium carbonate filled polypropylene/ethylene propylene diene terpolymer composites
Salmah Husseinsyah, Prof. Madya Ir. Dr.; Siti Rohana, Ahmad; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. (Trans Tech Publications, 2014)Inorganic filler, calcium carbonate (CaCO₃) was used as filler in the polypropylene (PP)/ ethylene propylene diene terpolymer (EPDM) composites. The composites were compatibilized with Maleic anhydride grafted polypropylene ... -
Effects of dynamic vulcanization on thermal properties of calcium carbonate filled polypropylene/ethylene propylene diene terpolymer composites
Siti Rohana, Ahmad; Salmah, Husseinsyah, Prof. Madya Dr. Ir.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. (Universiti Putra Malaysia Press, 2010-07)In this study, dynamic vulcanization process was used to improve the thermal properties of calcium carbonate filled composites. The composites were prepared using a Z-blade mixer at 180°C and rotor speed 50rpm. Thermogravimetric ...
