Carbon fiber industry typically per bundle of carbon fibers having greater than 48000 root (48K) is referred to as the large tow carbon fiber.

Shanghai Petrochemical is the first domestic enterprise to break through the industrialization technology of 48K large tow carbon fiber.

The large-tow carbon fiber precursor produced by the company is tempered in the oxidation furnace carbonization furnace, and when it comes out of the furnace, it is black and shiny, becoming a new high-strength, high-modulus fiber material with a carbon content of more than 95% .

In 2007, when Sinopec decided to deploy PAN -based carbon fiber research and development and industrialization, it handed over the development of the carbon fiber industry to Shanghai Petrochemical.

Joint research team to work together, in 2008 Nian 11 pilot plant built in March, 2009 Nian 3 months successfully developed a 12K strand.

In May 2016, they carried out the industrialization research test of carbon fiber 48K large tow precursor .

In August 2020 , Shanghai Petrochemical established the Advanced Materials Innovation Research Institute, aiming to carry out core technology research, focus on forming a complete set of carbon fiber engineering technology, and focus on promoting key core technology research and industrial innovation.
On this basis, in order to increase the production capacity of raw silk and realize the large-scale production of large tow carbon fiber, so as to reduce the production cost and use cost of large tow carbon fiber, Shanghai Petrochemical began to construct 24,000 tons / year raw silk and 12,000 tons / year .
