Carbon fiber powder is a fine particle obtained by grinding, screening and high-temperature drying of chopped carbon fiber filaments as raw materials. The mesh count ranges from 30 to 2000 mesh. It retains many excellent properties of carbon fiber, and has a fine shape, pure surface, large specific surface area, and is easy to be wetted and evenly dispersed by resin. It is an excellent reinforcing filler for composite materials. It can be compounded with materials such as resin, plastic, metal and rubber to enhance the strength and wear resistance of the materials. It is widely used in many fields, such as electronic chips, conductive plates, conductive floors, electronic machinery, anti-static industries, anti-static nets, building insulation, friction materials, chemical engineering, etc.
