Polyimide fiber has good application prospects. Cost reduction and efficiency increase are industry trends.

Polyimide fiber (PI fiber), also known as aramid fiber, refers to a fiber containing aroimide in its molecular chain. As a high-performance organic fiber, polyimide fiber has the advantages of excellent spinnability, high and low temperature resistance, dimensional stability, good safety, and long service life. It can be used to produce protective clothing, flame-retardant clothing,…
