Material Innovation: Performance Breakthrough of PAEK
PAEK (Polyaryletherketone) as the fourth-generation medical polymer material, achieves three core breakthroughs through unique molecular design:

1. Biomechanical adaptability: 3-4 GPa elastic modulus forms a gradient match with cortical bone (3-30 GPa), effectively avoiding the stress shielding effect of metal implants
2. Chemical stability: annual hydrolysis rate < 0.1%, passed the full set of biocompatibility certification according to ISO 10993-1
3. Imaging compatibility: X-ray transmittance > 90%, CT value 110-130 HU close to soft tissue, MRI without artifact interference

II. Material System: Molecular Structure Determines Performance Differences
PAEK family main members technical parameters comparison:
