HALOGENATED OR PARYLENE POLYMER COATING

摘要

A container, for example a syringe, cartridge, vial or similar article including a barrel or other vessel and a stopper, O-ring, plunger tip or piston. The vessel substrate defines a lumen and an internal sliding surface on the vessel substrate adjacent to the lumen. The stopper, O-ring, plunger tip or piston has an external sliding surface slidable in the lumen at least substantially in contact with the internal sliding surface. The internal sliding surface, the external sliding surface, or both are made at least in part of a parylene or halogenated polymer, which can be in the form of a coating or a bulk material. Methods of making the syringe, cartridge, or similar article using chemical vapor deposition, as by depositing the parylene or halogenated polymer directly or with intervening layers to define the external sliding surface, the internal internal sliding surface, or both are disclosed.
