Abstract
An arrangement includes an extruder crosshead, and an innermost rubber tube having an input portion a resident portion residing in the extruder crosshead, and an output portion. The arrangement further includes an ozone stream evolved from an ozone source, where the ozone stream is introduced into an ozone cavity of the extruder crosshead, and a continuous molten barrier forming material which is movable through a flow cavity in the extruder crosshead. A portion of the continuous molten barrier forming material which is emitted from the extruder crosshead is exposed to the ozone stream on an inner side of the portion to provide a heterogeneous surfaced barrier layer. The arrangement also includes a barrier coated rubber tube including the heterogeneous surfaced barrier layer and the output portion of the innermost rubber tube, where the heterogeneous surfaced barrier layer is disposed outward from the output portion of the innermost rubber tube.
