ABSTRACT:
This invention relates to a novel elastomeric foamed material which has surprisingly been found to exhibit a variety of unusual and desirable features both in its physical properties and in its process of manufacture. These foamed compositions of a lightly sulfonated elastomeric gum contain a nonvolatile polar plasticizer and preferably extenders such as oil and fillers. These elastomer foams exhibit an unusual profile of physical properties including melt reprocessability of fabricated articles, and high temperature reshaping of foamed objects while maintaining a good foam structure. These novel foams can be manufactured with relatively uniform cell structures and with small cell sizes at foam densities from near bulk density to less than 0.1 g/cc.
