PEEK (polyether ether ketone) is an advanced engineering plastic with excellent properties and a wide range of applications. The following is the performance analysis of PEEK material:

1. High temperature resistance: PEEK has excellent high temperature resistance and can maintain excellent performance at high temperatures. The long-term use temperature is 260℃, and the short-term use temperature can reach 300℃.

2. Chemical stability: PEEK has excellent chemical stability and can maintain stable performance in harsh environments such as strong acid, strong alkali and organic solvents. It is not easily eroded by chemicals, and will not cause corrosion and aging.

3. Mechanical properties: PEEK has stiffness and elasticity, especially good fatigue resistance under alternating stress, which is comparable to alloy materials. In addition, PEEK has excellent sliding properties and is suitable for applications where low friction coefficient and wear resistance are strictly required.

4. Dimensional stability: PEEK has excellent dimensional stability, which is very important for some applications, and changes in environmental conditions such as temperature and humidity have little impact on the size of PEEK parts, meeting the requirements of high dimensional accuracy.

5. Electrical performance: PEEK has excellent electrical performance, stable insulation performance and excellent voltage resistance. Therefore, PEEK is widely used in electronic, electrical and other fields.

6. Biocompatibility: PEEK has good biocompatibility and is widely used in the field of medical devices. It can be compatible with human tissue without adverse reactions.

7. Processing performance: PEEK has excellent processing performance, and can be molded by injection molding, extrusion, blow molding and other processing methods. At the same time, PEEK also has good secondary processing performance, can be mechanical processing, drilling, cutting and other operations.

8. Flame retardant: PEEK has good flame retardant performance, its oxygen index is as high as 44%, much higher than other engineering plastics. In situations where fire protection is required, PEEK is an ideal material choice.

9. Wear resistance: PEEK material has excellent wear resistance and low friction coefficient, second only to PEEK material at high temperature, high pressure and high friction conditions can still maintain good wear resistance, effectively extending the service life of mechanical equipment. Compared with metal,PEEK material will not rust or be corroded by oxidation, so it is also widely used in a variety of mechanical equipment.

10. Smoke and toxicity: PEEK has the least smoke in plastic products, and no acid gas is found. When decomposed at high temperatures, PEEK mainly produces carbon dioxide and carbon monoxide. Using the British aircraft test standard BSS7239, very low concentrations of toxic gases can be detected. The process involves completely burning 100 grams of a sample in a cubic meter space and then analyzing it for toxic gases. The toxicity index is defined as the ratio of the concentration of toxic gases normally produced to the lethal dose within 30 minutes. The PEEK450g index is 0.22. But no acid gas was found.

In general, PEEK material has excellent performance and a wide range of application areas, the future with the continuous innovation of technology and the continuous expansion of the market, PEEK material application areas will be further expanded, providing more opportunities for future development.
