| The good biocompatibility, processability and the option to pigment make the VESTAKEEP® Care-Grades an ideal material for the fabrication of medical devices with short time contact to human blood, tissue or bone for up to 30 days. Because of their combination of outstanding mechanical properties and their excellent resistance to common cleaning and sterilizing processes, VESTAKEEP® Care polymers are designed to develop your next generation medical devices. Key properties are Excellent biocompatibility Outstanding biostability Good resistance to commonly used sterilization methods like autoclaving and others Resistance to high-energy radiation such as gamma rays or X-rays X-ray transparency, no metal-typical shadows or artefacts in radiographs. Good combination of mechanical strength, wear resistance and impact resistance makes PEEK a good choice for high strength medical devices Good dimensional stability allows for manufacturing of high-precision parts Good electrical properties, especially electrical insulation, is important for medical equipment – for example HF endoscopes&& |
