Minnesota Wire,US company specializing custom design and production of cable assembiles for medical devices,now replace the thermoplastic vulcanizate (TPV) elastomers with Teknor Apex’s new styrenic thermoplastic elastomer (the new TPE-S).

“We’ve tested the new Medalist compounds and found them to have better tensile and elongation properties than TPVs before autoclaving and to retain more of these properties after multiple autoclave cycles—an important advantage in the many medical devices intended for reuse,” said Jeff Lewison, design engineer at Minnesota Wire. “In addition, the Medalist compounds are more stable in extrusion, and in injection molding their improved processability means that we can lower the pressures to reduce the likelihood of defects when we’re molding over delicate circuitry. Customers will like the fact that our product just looks and feels better.”

The TPE-S compounds, Medalist? MD-8421, MD-8431, and MD-8451, comprise a series within Teknor Apex’s Medalist product range, a diversified family of high-purity medical elastomers that also includes other TPE types, among them TPVs.

The white paper by Teknor Apex will provide test data comparing the three new Medalist compounds with a standard medical-grade TPV used in wire and cable. In tests measuring tensile strength and elongation, all three Medalist grades exhibited greater values for these properties prior to autoclaving and greater property retention after as many as 15 autoclave cycles.
