Among the greatest failings of previously proposed alternatives to PVC are those involving properties important in daily use by healthcare workers. Medalist MD-500 elastomers have exhibited performance comparable to PVC in:

  • Kink resistance. In many applications, tubing is used for infusion of fluids into the body. If the tube should be bent through a radius that is too tight, it collapses, with consequences that are potentially life-threatening.
  • Clamp resilience. To temporarily halt the flow of liquid, medical tubing is often clamped using either roller or hemostat clamps. Both compress the tube to block flow, and after release of pressure, the tube must recover and allow flow to resume in a short space of time.
  • Necking resistance. Necking is a phenomenon in which the diameter of a tube is permanently reduced when exposed to a longitudinal force.
  • Haptics or ‘feel.’ Most tubing sets are used manually, with the familiar feel of PVC being the accepted norm in the healthcare industry. In blind tests, experienced individuals from the device industry failed to distinguish between PVC and TPE tubing.

Extrusion and Fabrication

Teknor Apex has worked collaboratively with companies having expertise in medical tubing manufacture. In a demonstration run on a fully equipped, commercial-scale tubing extrusion line, equipment manufacturer American Kuhne Inc. achieved high-speed, tight-tolerance production of tubing from MD-585, an 85 Shore A Medalist compound. The company ran tubing with a 0.105 in. (2.67 mm) OD and 0.020 in. (0.508 mm) wall thickness at speeds up to 830 ft/min (253 m/min.). At a 600 ft/min (183 m/min) line speed, tolerances of +/- 0.0004 in. on the OD and +/- 0.0001 in. on the wall thickness were held.

To demonstrate the capabilities of Medalist MD-500-based tubing in post-extrusion processes, Teknor Apex worked with prominent medical device manufacturers Dunn Industries, Inc., which specializes in medical tubing, and Pelham Plastics Inc., with expertise in assembly techniques. The companies achieved good results in these techniques:

  • Cutting to length. This requires a wide processing window, close tolerances, and ease of cutting in-line with extrusion.
  • Hole punching posed no problems, even allowing for tube rotation producing a serpentine pattern; though this process is typically difficult for elastic materials because of stretching or tearing.
  • Tipping—the process of forming a tapered closure at the end of a tube—was carried out without need for pretreatment or release agents, which would require additional regulatory approvals. Cycles were fast, there was no sticking, tapers were consistent, and the aesthetic quality of the finished product was excellent.
  • Printing was carried out successfully using standard automated corona surface treatment and traditional pad printing with conventional inks. Teknor Apex suggested inks that could be used without the need for pre-treatment.
  • Insert molding, in which luers were applied to the ends of tubing, involved short cycle times, no tube distortion, and excellent bonding of the tubing to pre-colored luers made of either polypropylene or Medalist elastomers.
  • Attachment to standard connectors. Teknor Apex has developed patent-pending bonding systems involving both room temperature-cured and light-cured adhesives, enabling common-size TPE infusion tubing to achieve bonds exhibiting a retention force significantly greater than the minimum required by device manufacturers. In addition, Clean Room Devices LLC has developed an automatic fitting inserter that carries out high-speed assembly of tapered-barb connectors and tubing produced from Medalist MD-500 TPEs.
