Elastomer molded article, rubber material and O-ring using same

摘要

A film of a fluorine-type resin having a thickness of 500 mum or less is formed on a surface of an elastomer molded article by a vacuum deposition method. The resultant elastomer molded article having the film of the fluorine-type resin has a sticking force to a metal of 100 N or less in an environment of from 200° C. to 300° C. and has a weight reduction ratio of 1.0% by weight or less by irradiation of a mixed plasma containing oxygen and carbon tetrafluoride.
