Polyimide (PI) refers to a high molecular weight polymer containing an imide structure in the main chain of the molecular structure. Polyimide is a very large family. The main chain of high-performance PI is mostly composed of aromatic rings and hetero The ring is the main structural unit.PI has a high flame retardant rating (UL-94), good electrical insulation, mechanical properties, chemical stability, aging resistance, radiation resistance, low dielectric loss, and these properties are in a wide temperature range (-269℃-400℃), there will be no significant changes, and it is known as the "problem-solving expert", and its performance is at the top of the polymer material pyramid. The polyimide material has increased the average use temperature of the polymer material by more than 100°C, and has become a polymer material with good high temperature resistance that can be actually used at present.
Polyimide fiber is an important high-performance fiber. The high temperature resistant polyimide fiber is one of the organic synthetic fibers with higher temperature. It can be used at 250~350℃. It is compatible with aramid and polyphenylene sulfide fibers in terms of light resistance, water absorption, and heat resistance. Compared with both are more superior, the strength of high-performance polyimide fiber is about 1 times higher than that of aramid fiber, and it is one of the organic synthetic fibers with better mechanical properties at present.
Polyimide fiber plays an important role in many fields due to its excellent mechanical properties and high temperature resistance, mainly including the following aspects:
(1) Aerospace: Lightweight cable sheath, high temperature resistant special braided cable, large-caliber unfoldable satellite antenna tension cable, etc.
(2) Environmental protection field: industrial high temperature dust removal filter material.
(3) Fire-resistant materials: high-temperature-resistant and flame-retardant special protective clothing, cold-proof clothing, flame-proof clothing for racing cars, etc.
