Abstract

An improved composite rubber material having a baked layer of fluorine resin of 10 microns to about 1 millimeter in thickness is proposed. The coated layer of fluorine resin is baked at a temperature over 400.degree. C. for not more than 7 minutes. This assures that the fluorine resin is baked without deteriorating the rubber material.
