Kc. Guriya et al., RHEOLOGICAL PROPERTIES OF EPDM-COMPOUNDS - EFFECT OF BLOWING AGENT, CURING AGENT AND SILICA FILLER, Kautschuk und Gummi, Kunststoffe, 51(2), 1998, pp. 134-138
Apparent shear stress, apparent viscosity and die swell of the gum and
silica filled EPDM rubber compounds were determined with the Monsanto
Processability Tester. There is a significant reduction in the stress
and viscosity by blowing agent in the presence of curing agent vs. it
s absence. Viscosity reduction factor is found to be dependent on the
blowing agent loading, shear rate and temperature.
