WEB EXCLUSIVE: Solvay Specialty Polymers USA, LLC, Alpharetta, Ga., has expanded its range of Zeniva PEEK resins for implantable medical devices with a radio-visible grade. New Zeniva ZA-520 contains an image-contrast additive for good visibility with x-ray, CT, and MRI imaging systems—without the artifacts common with metallic components. In addition, PEEK reportedly offers benefits over metals such as titanium and cobalt chrome alloy for applications such as intervertebral devices (pictured). These include an elastic modulus that is close to that of bone. The new compound is available as resin for injection molding or as machinable rod stock.
