AKSOPEEK® Performance and characteristics
AKSOPEEK® Passed biocompatibility testing, the material has no cytotoxicity, mutagenicity, carcinogenicity, and does not cause allergies.
The elastic modulus is similar to that of cortical bone, with physical properties similar to human bones. The texture is sturdy, and the stress borne by the bone is not entirely borne by the implant, making the bone healthier.
Corrosion resistance, radiation transparency, no artifacts on X-ray images, and the ability to perform surgery with the assistance of CT scanning or magnetic resonance imaging.
