Polyimide short fibers are short fibers made of polyimide (PI) material. Polyimide is a high-performance polymer with excellent high-temperature resistance, chemical resistance, and mechanical strength.
Polyimide short fibers typically have shorter fiber lengths, typically ranging from millimeters to centimeters. These short fibers can be obtained through spinning, cutting, or other processing methods. Compared to long fibers, short fibers are easier to mix, disperse, and process with other materials.
Polyimide short fibers can be used in applications such as reinforcing composite materials, fillers, and injection molding. They can provide increased strength, stiffness, and heat resistance to the material, improving the material's mechanical performance and stability. In addition, polyimide short fibers can also be used to manufacture insulation materials, sealing materials, friction materials, etc.
The characteristics of polyimide short fibers include good high-temperature resistance, excellent chemical stability, and mechanical strength, making them play an important role in various high-demand applications.
