  • Hollow Body Made of Plastic Having a Barrier Layer on its Inner Surface and a Method for Manufacturing the Same
    Publication number: 20110305856
    Abstract: Hollow body made of plastic having a fluorinated inner surface according to the present invention is characterized in that in one or more defined regions of the inner surface, the fluorine occupancy deviates from the mean fluorine occupancy by at least ±10%. Furthermore, a method for the production of a hollow body made of plastic having a fluorinated inner surface is presented, in which, for the formation of fluorocarbon and hydrofluorocarbon compounds, the inner surface is exposed to the action of a defined amount of a fluorine-containing treatment gas and the hollow body is thermostatted on its outside so that the temperature in one or more defined regions of the outside is at least ±2° C. above/below the mean temperature of the outside.
