摘要：
A syringe stopper that is suitable for use in syringes without silicone oil or other liquid lubricants. The invention provides a low friction barrier between an elastomeric stopper material and a therapeutic in the syringe. The barrier may inhibit materials from leaching from the elastomer material or from extraction of compounds from medicants by the elastomer. A process is also described that allows for molding thin barrier layers while allowing adequate bonding with the elastomer.
