The formation of a layer of fluorine-containing ingredients on the surface of a vulcanisate used in the manufacture of mechanical rubber goods, (MRGs) can promote a reduction in the friction coefficient of the MRGs and increase their resistance to ozone ageing. One method of forming a constantly regenerative layer on the surface of MRGs involves the transfer of an ingredient, introduced at the mixing stage, from the interior to the exterior of the elastomer. An excess quantity of the ingredient, exceeding its equilibrium solubility in the elastomer is introduced into the composite, and the formation of a surface layer is connected with the separation in the elastomer-ingredient system. This work investigates the possibility of the formation of a surface layer with an equilibrium content of different fluorine-containing ingredients in the elastomer, and to determine the time of retention of this layer. 7 refs.
