As a high-performance, high-temperature material, PEEK material has been widely used in aerospace, medical, automotive, electronics and other fields. So what is PEEK material? What are its unique properties and application range? Below, we will introduce PEEK material in detail for you.

1. the characteristics of PEEK material

PEEK (polyetherimide) is a high-performance polymer material, which performs well at high temperatures, has excellent characteristics such as chemical resistance and abrasion resistance. Compared with other engineering plastics, PEEK has higher thermal stability and chemical resistance, and its structure can withstand higher pressure and wear, and can withstand higher tensile and extrusion forces.

2. The performance of PEEK materials

1. Mechanical properties

The mechanical properties of PEEK are very good. At high temperatures, the mechanical properties of PEEK materials generally do not decrease. The tensile and flexural strength of PEEK is similar to that of most metals, and it has excellent fatigue properties, making it an ideal mechanical structural material.

2. Chemical performance

PEEK material has excellent chemical resistance and can withstand most acids, alkalis and organic solvents. The oxidation resistance and UV resistance of PEEK materials are also excellent.

3. High temperature stability

PEEK material can be used for a long time at extremely high temperatures, and can withstand high shear stress and high pressure. It has a melting point of up to 343°C and can withstand high temperatures of up to 300°C.

3. the application range of PEEK materials

PEEK materials have a wide range of applications and can play an important role in aerospace, medical, automotive, electronics and other fields. Due to the high temperature and chemical stability of PEEK material, it is often used to manufacture high temperature sealers, ultrasonic probes, nuclear fuel rods, oil platform equipment and chemical valves.

4. The advantages of PEEK materials

1. Withstand high temperature and chemical corrosion

2. Strong mechanical properties

3. Wear resistance and impact resistance

4. Good
dimensional stability
5. Good insulation performance

6. High weather resistance

7. Can be used in food contact

PEEK as a high-performance, high-temperature material, it can withstand high pressure, high temperature, chemical corrosion, etc. in various extreme environments. With the continuous development of science and technology, the application scope and market prospect of PEEK materials are becoming more and more broad.
