Medalist™ MD-84368 (PRELIMINARY DATA)

About
Medalist MD-84300 series are high performance thermoplastic elastomers designed specifically for extrusion and injection molded electrical applications in the medical and healthcare industry. The Medalist MD-84300 series are a better alternative to traditional TPVs used in such applications. Medalist MD-84368 is a medium hardness, low density grade with good electrical properties and can be sterilized by autoclave, ETO, or gamma radiation.&&
