PolyOne GLS: Self-sealing TPEs for medical infusion

The product has very good self-sealing performance and resistance to coring, addressing major drawbacks of traditional materials. PolyOne said that it is currently working with key pharmaceutical OEMs in applications that leverage the multiple advantages of this material. By replacing traditional stopper and septum materials with insert-moulded Versaflex HC, the following benefits can be obtained:

• Excellent self-sealing
  Formulated specifically for resealing applications, Versaflex HC avoids coring contamination that is characteristic of traditional vulcanised rubber, which can leave particles of material behind during needle insertion.
• Resistance to coring
  Testing Versaflex HC for resealing and coring performance with needles as large as 16 gauge achieved very good results including good resealing after multiple penetrations.
• Enhanced purity
  Because it does not use sulphur, zinc or other crosslinking agents common in vulcanised rubber, Versaflex HC can provide superior purity to reduce the risk of leaching and interacting with sensitive pharmaceuticals.
• Reduced manufacturing cost
  Versaflex HC processes in a simple, one-step injection moulding operation vs. the multiple steps needed for vulcanised rubber. In addition, these materials do not need the washing step required with conventional rubber.
• Streamlined regulatory compliance
  The material meets the requirements of the ISO 15759 standard for medical infusion equipment and can be steam autoclaved using temperatures up to 126 °C.

PolyOne GLS offers a comprehensive TPE portfolio including the OnFlex and Dynaflex TPE compounds, Versaflex TPE alloys, Dyn­alloy OBC compounds, Versalloy and Versollan elastomer alloys. The company also distributes Kraton compounds and Santoprene TPVs in selected regions.
