Natural Na+ montmorillonite (MMT) microclay and organo-treated MMT nanoclay were independently filled in a high-density polyethylene (HDPE) polymer and HDPE–glass fiber (GF) composite and the rheological and mechanical properties were examined. The addition of nanoclay in the HDPE polymer and HDPE–GF composite increased the melt viscosity, rate of crystallization, and crystalline fraction. Addition of Na+ MMT clay on the other hand did not affect the crystalline properties, but increased the melt viscosity marginally. The composite was also examined after the addition of a polyethylene-grafted maleic anhydride-based compatibilizer. It was found that the compatibilizer improved the dispersion of clay particles in the polymer matrix which in turn affected the rheological and mechanical properties of the composite. Improved tensile and wear properties were observed in nanoclay-filled composites when compared to microclay-filled composites.
