Title Barrierity of hydrogenated butadiene-acrylonitrile rubber and butyl rubber after exposure to organic solvents
Bibliographic information 2011, Vol.17, No.1, p.41-47. Illus. 10 ref.
Abstract Resistance of chemical protective clothing primarily depends on its constituent materials, in particular on the type of polymer used for coating the fabric carrier. This article reports on systematic investigations on the influence of the cross-linking density of an elastomer and the composition of a cross-linked elastomer on its resistance to permeation of selected organic solvents. Tests of barrier material samples made from nonpolar butyl rubber (IIR) and polar hydrogenated butadiene-acrylonitrile rubber (HNBR) showed that in rubber-solvent systems with medium thermodynamic affinity, cross-linking density influenced resistance to permeation and the polarity of the system had a significant influence on the barrier properties.
