Abstract: The invention relates to polymer foil comprising at least one polymer layer coated with a barrier glass coating of an oxide composition, wherein said oxide composition comprises the element Si in the form of an oxide network, the oxide composition preferably comprises Si and at least one other element X in an oxide network. The oxide network may preferably be applied using plasma. The foil may be a multi-layered foil comprising a plurality of layers, at least one of the layers being a barrier glass coating. The foil has good barrier properties.

Abstract: The invention relates to a method of providing a rubber material from a rubber containing waste material. The method comprises the step of subjecting the waste material to a treatment with an extraction solvent in a reactor at a pressure above atmospheric pressure, wherein the extraction solvent comprises an effective amount of carbon dioxide. The extraction may be performed in one or more dynamic and/or one or more static steps, to provide a sufficient extraction without damaging the material. The rubber containing waste material may further be subjected to an impregnation step, which may be performed simultaneously with the extraction step, after the extraction step or overlapping with the extraction step. The invention also relates to a rubber material comprising low amounts or is essentially free of alkylated aromatic oils and heavy metals in the form of inorganic and organic salts.
