METHOD OF INCREASING THE WEAR RESISTANCE OF RUBBER SEALS

The subject of the invention is a method of increasing the wear resistance of rubber seals, for example, for sealing shafts, pistons, rods, etc., by applying an antifriction coating, in particular Teflon, to their surfaces. The antifriction Teflon coating is made in the form of a porous film and is pressed onto a rubber base in the process of forming the sealing element, whereupon adhesion of the coating to the base is accomplished by the rubber mass flowing into the pores of the film and by subsequent vulcanization.
