Wire Compound in Medical Elastomer Range Fully Compliant With Medical Requirements

The first wire and cable compound in the Medalist family of medical elastomers is formulated and produced in accordance with stringent medical-industry requirements yet draws on technology with a long track record of success in non-medical insulation and jacketing applications.

Like other Medalist elastomers, Medalist MD458 compound is a high-purity formulation that has passed ISO 10993-5 cytotoxicity testing, is RoHS and REACh compliant, and is manufactured in Teknor Apex’s dedicated medical compounding facility in St. Albans, VT. At the same time, the new compound provides the same electrical performance, elevated service temperature rating, and resistance to chemicals and sunlight as the company’s Elexar EL8431, a thermoplastic elastomer (TPE) with more than two decades of service in wire and cable.

“As an exact medical-grade analog to a proven Elexar compound, Medalist MD458 draws on the extensive experience of Teknor Apex in serving both the electrical and medical sectors,” said Nick Sandland, senior medical market manager. “It is our belief that this new compound is the first elastomer to be fully compliant with the standards and practical performance requirements of both industries.”

Medalist MD458 has a Shore A hardness of 70, a flammability classification of HB (UL-94), and a maximum continuous operating temperature rating of 105ºC (UL-1581). It has passed standard tests for oil resistance after seven days at 60ºC and UV resistance after 720 hours. These properties lend themselves to applications in hospital and healthcare environments requiring excellent flexibility, durability, and chemical resistance.
