Effect of clay on properties of ionic thermoplastic elastomer based on EPDM

Abstract

Incorporation of hard clay causes improvement in most of the physical properties of zinc-sulfonated EPDM of high ethylene content. Zinc stearate reduces the melt viscosity of the clay-filled zinc-sulfonated EPDM during high-temperature processing, but does not adversely affect the physical properties at ambient temperatures. Studies include the measurement of physical properties, scanning electron microscopy (SEM), processability studies in a Monsanto processability tester (MPT), and dynamic mechanical analyses (DMA). © 1996 John Wiley & Sons, Inc.
