Abstract

Polipropilen can be modified with bentonite (clay) that contain 50-80% montmorillonite. Montmorillonite has nano sized layers so that can be used as nanofiller on polipropilene-nanocomposite production. This research was done to find effect of montmorillonite composition on polipropilen-nanocomposite production to the mechanical properties. Mechanical tests in this research are tensile strength and hardness. Nanocomposite was produced through Melt Compounding method using injection molding equipment. This research used polipropilen (PP) and masterbatch that contain 0; 2,4, 3,6; and 5,4% montmorillonite composition. Result of the observation shows that nanofiller addition can increase mechanical properties of material. Optimum tensile strength was 32,88 MPa and was obtained when montmorillonite composition is 2,4%. Optimum hardness 72 mN was obtain when montmorillonite composition is 3,6%.
