Advantages:

1. Wear resistance and stability: PEEK has excellent wear resistance and chemical stability, which can maintain stable performance in high temperature and corrosive environment, and is not easy to deteriorate or wear.

2. High strength and light weight: PEEK has the characteristics of high strength and light weight, and can be used to manufacture thin and strong medical equipment to improve the portability and use effect of the equipment.

3. Non-toxic and tasteless: PEEK is non-toxic and tasteless, harmless to the human body, and meets the requirements of material safety in the medical field.

4. Biocompatibility: PEEK has good biocompatibility, does not cause allergies or immune reactions, and has small stimulation of biological tissues, so it can reduce rejection when implanted in the body.

5. X-ray transmittance: PEEK has good X-ray transmittance and does not affect medical imaging analysis.

Cons:

1. Processing difficulty: the processing technology of PEEK is relatively complex, requiring professional equipment and skills, so the processing cost is relatively high.

2. High cost: Compared with other ordinary plastics, PEEK has a higher price, and the cost of manufacturing medical equipment also increases correspondingly.

3. Sensitive to temperature and humidity: PEEK is sensitive to changes in temperature and humidity, which may affect its performance and stability. Therefore, it is necessary to pay attention to the control of temperature and humidity during storage and use.

4. Wear resistance and chemical corrosion resistance need to be improved: compared with some other materials, such as titanium alloy, PEEK's wear resistance and chemical corrosion resistance may be slightly inferior, and it is necessary to pay attention to protection and maintenance during use.

In summary, the application of PEEK in the medical field has a wide range of prospects, especially in medical supplies. However, it is necessary to pay attention to its shortcomings such as high cost, difficult processing and sensitivity to temperature and humidity. When choosing to use PEEK as a medical material, it is necessary to consider its advantages and disadvantages and the requirements of the actual use environment.
