摘要

The rheological behavior of ethylene propylene diene monomer (EPDM) compounds containing ground EPDM waste (W-EPDM) of known composition was studied by using a Monsanto processability tester in a temperature range of 90-110degreesC and a shear rate range of 306.7-1533.24 s(-1). It is found that the shear viscosity decreases slightly with increasing W-EPDM loading because of wall slip that results from the migration of lubricants from the W-EPDM. The addition of W-EPDM to raw EPDM results in a decreased die swell at all temperatures and shear rates. SEM photomicrographs of the EPDM extrudate surface show improved surface smoothness and reduced extrudate distortion when EPDM is blended with W-EPDM. (C) 2003 Wiley Periodicals, Inc.
