What is 3k polyacrylonitrile-based carbon fiber precursor?

3k polyacrylonitrile-based carbon fiber precursor is a type of carbon fiber precursor. "3k" means that there are 3,000 single filaments in a bundle of this carbon fiber precursor. It uses polyacrylonitrile as the main raw material and is made through solution spinning or melt spinning. This precursor is the basic material for manufacturing high-performance carbon fiber. After subsequent complex processes such as pre-oxidation and carbonization, carbon fiber with excellent performance can be obtained.


Shanghai Tanchain can supply tens of thousands of tons of polyacrylonitrile carbon fiber precursor annually. Our carbon fiber polyacrylonitrile-based precursor has stable quality and ultra-high performance, which can meet the needs of most customers in the market.
