Evaluation of physical properties and curing characteristics of silica-filled ethylene–propylene–diene terpolymer in the presence of chloroprene rubber

Authors


Abstract

The effect of addition of chloroprene rubber (CR) on the dispersion of silica in EPDM (ethylene–propylene–diene terpolymer) was studied. It was observed that physical properties of the vulcanizates could be significantly increased at the EPDM : CR blend ratio of 92.5 : 7.5. SEM micrographs also indicated that incorporation of CR into EPDM improves the network structure of the resulting vulcanizates. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 196–200, 2004
