In the healthcare and biomedical field, PEEK (Polyether Ether Ketone) and PPSU (Polyphenylsulfone) demonstrate unique advantages.

PEEK features excellent biocompatibility, mechanical strength and corrosion resistance. It is widely used in manufacturing orthopedic implants such as artificial joints and spinal fusion devices, which can integrate well with human tissues and provide long-term stable support. PPSU, on the other hand, is favored for its outstanding high-temperature sterilization resistance, toughness and chemical stability. It is commonly adopted to produce medical devices including surgical instrument handles and baby feeding bottles.

For instance, in orthopedic surgeries, artificial joints made of PEEK can replace damaged joints and help patients regain normal mobility. Meanwhile, baby feeding bottles crafted from PPSU can withstand repeated high-temperature sterilization, ensuring safety and reliability.

In addition, PEEK can also be applied in dental restoration, while PPSU is suitable for manufacturing housings of medical equipment to protect internal precision components. The application of these materials plays an important role in improving medical quality and safeguarding health.
