ABSTRACT:
A skin barrier composition is provided which is composed of a mixture of a copolymer resin of ethylene and vinyl acetate (EVA), at least one water absorbing particulate hydrocolloid or polymer, and a water-insoluble dry tack-providing elastomer such as polyisobutylene. The composition after mixing and molding, is subjected to ionizing irradiation to form cross-linked polymer networks of the EVA or EVA with another polymer cross-linking by irradiation. The compositions have exceptional properties for use as barrier sheets, rings, or strips in ostomy, wound drainage, and incontinence devices.
