Abstract
Organoclay was compounded with EPDM using a two roll and cured by conventional sulfur curing system. The organoclay content was progressively increased from 0 to 15 phr of the EPDM rubber. The mechanical properties of the EPDM vulcanizates were evaluated by an Ekktron tensile testing machine. It has been found that tensile properties increased with nanoclay content. The observed trend was related mainly to the strong interaction between the rubber matrix and the nanoscaled filler (organoclay in this case) and subsequently to the improved crosslink density. Such improvement was attributed to the small size of the filler particles and to the amine functionality in the organoclay structure.
