Have you ever heard the word PTFE? It is a very characteristic material, and many high-tech fields cannot do without it. The most familiar PTFE should be the common "silver tube"-fluoroplastic silver tube. So, what kind of material is PTFE?

1. historical

PTFE is the abbreviation of Polytetrafluoroethylene, Chinese name PTFE. It was first successfully prepared in the 1930 s by DuPont chemists Wallace Carothers Hume and Dr. Roy J. Plunkett in an extremely harsh laboratory environment. PTFE was first used in high-tech fields such as missiles and spacecraft. With the continuous improvement of production technology and technological progress, its application fields are becoming more and more extensive.

2. characteristics

PTFE has a variety of characteristics, is a necessary material for many high-tech products, has the following characteristics:

1. High physical stability: corrosion resistance, waterproof, anti-pollution, anti-ultraviolet, etc.

2. excellent thermal stability: can withstand high temperature environment and very low temperature, while the melting point of PTFE is high, the melting point is 327 ℃.

3. Good mechanical properties: PTFE has excellent elasticity, high strength, wear resistance, tensile properties and anti-vibration properties.

4, non-toxic, tasteless: It is worth mentioning that PTFE is a non-toxic, tasteless material, and high temperature resistance, so in medical and food packaging also has a wide range of applications.

3. application field

1. chemical industry: PTFE has strong resistance, excellent corrosion resistance and pollution prevention, so it is widely used in the production of chemical pipelines, valves, pumps, etc.

2. Mechanical field: PTFE also has a wide range of applications in the field of mechanical equipment, which is usually called "oil-free field. Such as self-lubricating bearings, seals, cables and other equipment.

3. Medical field: PTFE has excellent biocompatibility, so it is widely used in the field of medical device production. Such as artificial heart valves, medical pipes and other medical devices.

4. Aerospace field: PTFE is widely used in the manufacture of missiles, spacecraft and other equipment. In these equipment, PTFE has excellent corrosion resistance and pollution resistance, and can adapt to extreme high and low temperature environments.

4. prospect

PTFE has a very broad application prospect in various fields, but due to the limitation of its manufacturing process and high cost, there is no high-performance PTFE product with a wide range of practicability. In order to better promote the further development of PTFE, more and more technology companies have begun to gradually improve the production process of PTFE, and at the same time develop more PTFE products suitable for different fields of application scenarios, bringing great market prospects.

conclusion

PTFE as a high performance material can play an important role in different fields. We hope that more people can pay attention to and study this material, and make its application field wider, and give full play to the excellent performance of PTFE.
