Preparation and Characterization of Silicone Rubber/EPDM/Nanoclay Nanocomposites

In this study nanocomposites based on SR/EPDM containing 30 wt% of EPDM and 9 phr of clay (Cloisite 15A) were prepared with a two-roll mill and characterized by XRD and mechanical properties were measured through tensile test. XRD patterns indicated the agglomeration of clay in SR and exfoliation of clay in EPDM. Mechanical properties showed that adding EPDM to SR decreases the mechanical strength of the blend. Moreover, poor rubber-filler interaction of SR and clay weakened the mechanical properties while strong interaction of EPDM and clay improves these properties
