Event: ANTECThis paper investigates the effects of clay on the mechanical properties of injection molded high-density polyethylene (HDPE)/clay nanocomposite foams that contained a very small amount of clay in the range of 0.1 to 1 wt%. Nanocomposite compounds were prepared by a melt blending masterbatch process and injection molded by using an advanced structural foam molding machine inwhich N2 was used for foams as a physical blowing agent.The results suggest that the addition of clay increased the flexural strength and modulus of both solid and foam nanocomposites as its contents were increased. The results also indicate that the foam nanocomposites always exhibited lower flexural properties but higher notched Izod impact strength than solid nanocomposites at each given clay amount.
