ABSTRACT:
A method of producing fluorinated elastomeric articles having reduced coefficients of friction, improved wear life and improved resistance to fluid permeability. A thermoplastic elastomeric article is exposed to gaseous fluorine in a reactor vessel under reaction conditions sufficient to create a fluorinated material on the external portions of the elastomeric article, which fluorinated material extends inwardly into the matrix of the article, without promoting degradation of the tensile properties of the article.
