Medalist Medical TPEs for Syringe Plunger Stoppers

Plunger stoppers serve as a key component of syringes or syringe-style dosage systems, functioning to preserve the integrity of the drug or chemical by providing an exceptional seal. Choosing the right material is crucial to the plunger stopper's performance. The stopper material needs to be chemically inert to minimize the risk of interaction with the syringe contents. A low coefficient of friction is required for optimal gliding performance against the glass or plastic barrel. Teknor Apex offers an entire portfolio of Medalist® medical-grade thermoplastic elastomers (TPEs) suitable for a variety of stopper designs and requirements.
