Polyimide fiber (PI fiber for short) is a high-performance polymer fiber made by spinning with polyimide resin or polyamic acid as the spinning slurry. Its molecular chain contains aromatic imide groups, which makes PI fiber have the characteristics of high strength and high modulus, and also has multiple properties such as high and low temperature resistance, radiation resistance, and flame retardancy.

‌Characteristics of polyimide fiber

Polyimide fiber is a high-performance organic fiber with excellent comprehensive performance, known as the "king of plastics". It can simultaneously have very good mechanical properties, high and low temperature resistance, self-extinguishing properties, radiation resistance, as well as excellent dielectric properties, corrosion resistance, temperature rise compatibility, and low density.

1. Oxidation resistance, low water absorption and unique cross-sectional structure make it very useful in filter materials, especially in high-temperature smoke filter materials.

2. Good spinnability, permanent flame retardancy, dimensional stability and safety, and extremely low thermal conductivity make polyimide an ideal raw material for various protective clothing.

3. Polyimide is also a reinforcing agent for advanced composite materials. With the development of my country's aerospace industry, it has shined in the aviation field and special protection.

4. Polyimide fiber also has the advantages of high elastic modulus, radiation resistance, and light weight. With the deepening of research, the reduction of the cost of polyimide and the promotion of mass production, it will definitely have a better development prospect in the future.

Application of polyimide fiber

PI fiber has a wide range of applications, including but not limited to:

‌Aerospace‌: It has excellent stability in high temperature and radioactive environments, and is suitable for spacecraft insulation materials, protective clothing, etc.

‌Mechanical and electrical industry, chemical industry‌: used to manufacture high-temperature resistant filter materials, insulation materials, etc.

‌Automotive Industry‌: Used to manufacture high-temperature resistant automotive parts to improve the overall performance and safety of the car.

‌Environmental protection field‌: The high strength and corrosion resistance of PI fiber make it an ideal material for making environmentally friendly high-temperature dust removal filter bags.

In recent years, with the improvement of polyimide synthesis technology and fiber spinning technology, the industrialization process of PI fiber has gradually accelerated, and its role in aerospace, national defense, new building materials, environmental protection, fire protection and other fields has become increasingly apparent
