High-performance EPDM/organoclay nanocomposites by melt extrusion

Abstract. Ethylene-propylene-diene terpolymer (EPDM)/organoclay nanocomposites were prepared by melt extrusion in a twin-screw extruder. The organoclay was characterized by XRD and TGA. As observed by transmission electron microscopy (TEM), the organoclay particles were exfoliated in EPDM. The tensile strength of the nanocomposites increased to 12.3 MPa at the same 3.0 phr amounts of fillers, …
