Process for the manufacture of industrial rubber articles

Abstract

A process for the manufacture of industrial rubber articles comprises vulcanization of a rubber mix, wherein prior to vulcanization the rubber mix is treated with a fluoroorganic compound and after vulcanization the articles are placed into a sealed chamber with the pressure therein below 10 Pa. An electric glow discharge is ignited in the chamber and the articles are treated therewith. The treatment with the electric glow discharge is stopped when a residual pressure in the chamber of below 100 Pa is reached. The process for the manufacture of industrial rubber articles according to the present invention makes it possible to produce articles with a coefficient of friction on their surface of from 0.2 to 0.6 depending on the type of rubber and enables an increase in productivity of machines and apparatus.
