Medical equipment PEEK can withstand 3000 cycles of autoclaving at 134°C. This feature meets the high sterilization requirements and the manufacture of surgical and dental equipment that requires repeated use, plus its creep resistance and water resistance. Decomposability, it can be used to manufacture various medical devices that require high-temperature steam sterilization. The most important thing is that PEEK is non-toxic, light, and corrosion-resistant. It is the material closest to human bones. Therefore, PEEK can be used instead of metal to make human bones.
