Permeability Studies

In this paper, gas permeability studies were performed on materials based on natural rubber/acrylonitrile butadiene rubber blends and nanoclay incorporated blend systems. The properties of natural rubber (NR)/nitrile rubber (NBR)/nanoclay nanocomposites, with a particular focus on gas permeability, are presented. The measurements of the barrier properties were assessed using two different gases—O2 and CO2—by taking in account the blend composition, the filler loading and the nature of the gas molecules. The obtained data showed that the permeability of gas transport was strongly affected by: (i) the blend composition—it was observed that the increase in acrylonitrile butadiene rubber component considerably decreased the permeability; (ii) the nature of the gas—the permeation of CO2 was higher than O2; (iii) the nanoclay loading—it was found that the permeability decreased with the incorporation of nanoclay. The localization of nanoclay in the blend system also played a major role in determining the gas permeability. The permeability of the systems was correlated with blend morphology and dispersion of the nanoclay platelets in the polymer blend.

Vulcanization Process

Abstract The objective of the work is to prepare compatible, coherent and technologically feasible blends comprising non-polar EPDM rubber and polar carboxylic-acrylonitrile-butadiene rubber (XNBR). Using an efficient sulfur vulcanization system containing bis(diisopropyl) thiophosphoryl disulfide (DIPDIS), a coupling agent cum accelerator, EPDM-XNBR blend has been co-vulcanized. The blend vulcanizates thus produced exhibit substantially enhanced physical properties which are superior to those of either component. The compatibility of the rubber blends as judged by SEM micrographs can further be improved through a two-stage vulcanization process which promotes interphase crosslinking between the polymer phases. The interphase crosslinking was recognized from swelling experiments. The study of the blends containing carbon black reveals a profound increase in physical properties of the vulcanizates as compared to those of gum vulcanizates. The SEM micrographs of the blend vulcanizates both in one-stage and two-stage distinctly indicate the blend morphology, which accounts for the significant improvement in physical properties of EPDM-XNBR blends through in situ reactive compatibilization. A reaction scheme for the interphase crosslinking has been proposed for the co-curing of EPDM-XNBR blend.
