ABSTRACT:
In order to guarantee that individual elastomeric components used for medicinal or pharmaceutical purposes have improved inertness and static and sliding friction properties, a suitable layer is provided on the elastomeric components for this purpose by the method of the invention. This method includes providing an extended flat mat made of elastomeric material including connected protruding elastomeric components; coating at least one side of the mat including the connected elastomeric components by means of a PECVD or PICVD method to provide a silicon dioxide layer containing carbon, hydrogen and/or nitrogen on the at least one side of the mat; and punching the connected elastomeric components out of the mat to form individual unconnected elastomeric components, each at least partially coated with a portion of the layer.
