Abstract :Polymer nanocomposites represent a new alternative to conventionally filled polymers. Because of their nanometer sizes, filler dispersion nanocomposites exhibit markedly improved properties when compared to the pure polymers or their traditional composites. These include increased modulus and strength, outstanding barrier properties, improved solvent and heat resistance and decreased flammability. In this study, mechanical, thermal and morphological properties of the high density polyethylene insert ignore into journalissuearticles values(HDPE); composites filled with nano zinc oxide ZnO);, magnesium hydroxide [ Mginsert ignore into journalissuearticles values(OH); 2 ] and  calcium carbonate insert ignore into journalissuearticles values(CaCO 3 ); were investigated. The structure and properties of the composites are characterized using a scanning electron microscopy insert ignore into journalissuearticles values(SEM); and Energy dispersive X-ray spectroscopy insert ignore into journalissuearticles values(EDS);. Furthermore, HDPE composites were subjected to examinations to obtain their tensile strengths, yield strengths, elasticity modulus, % elongation, Izod impact strength, hardness, wear strengths, heat deflection temperature insert ignore into journalissuearticles values(HDT);,Vicat softening point and melt flow index insert ignore into journalissuearticles values(MFI);.
