Solvay Specialty Polymers’ Zeniva ® polyetheretherketone (PEEK), one of four products comprising its family of Solviva® Biomaterials offered for use in implantable devices, successfully passed biocompatibility testing at the China Food and Drug Administration’s Tianjin Medical Device Quality Supervision and Inspection Center.
Zeniva PEEK boasts a modulus very close to that of cortical bone, plus excellent fatigue resistance and toughness. It is offered for use in implantable medical devices for spine and orthopaedic applications. Zeniva PEEK may offer advantages over metals, such as reduction of stress shielding, no heavy metal allergy or ion erosion and radiolucent properties that allow x-ray and CT scanning procedures without interference.
Solviva Biomaterials can be sterilized using all conventional methods including gamma radiation, ethylene oxide, and steam. These sterilizable products are available in grades for injection molding or extrusion, as well as stock shapes for machined components.
