Shanghai Petrochemical plans to build a carbon fiber project with an annual production capacity of 12,000 tons
Thread Content
Sinopec Shanghai Petrochemical plans to invest in the construction of a project for producing 24,000 tons per year of precursor fibers, as well as 12,000 tons per year of 48K large-tube carbon fibers. This investment project is expected to require an investment of around 3.5 billion yuan. The project utilizes self-developed technology to build 2 series of filament production lines, with a design capacity of 12,000 tons per year per series, as well as 6 carbon fiber production lines, each with an annual production capacity of 2,000 tons. The construction period is approximately 4 years.

Shanghai Petrochemical possesses a domestically developed, unique wet-process for producing NaSCN (sodium thiocyanate), as well as a set of technologies with independent intellectual property rights. It currently has an industrial production capacity of 3,000 tons of polymers, 3,000 tons of precursor fibers, and 500 tons of carbon fibers; in addition, a facility for producing 1,000 tons of carbon fibers is under construction. Each fiber bundle of the carbon fiber products consists of 12,000 fibers, meaning they are 12K fiber bundles.
Carbon fiber is mainly concentrated in three fields: aerospace small tow, industrial small tow, and industrial large tow. Small-tow carbon fibers are focused on industries such as aerospace and military applications, while large-tow carbon fibers are aimed at general-purpose civilian markets such as wind turbine blades, rail transportation, and vehicle lightweighting. The 48K large-tow carbon fiber product is the most widely used type in the market. In China, there is a strong demand for large-tow carbon fibers in areas such as rail transit, vehicle lightweighting, oil and gas fields, construction, drones, and large aircraft, offering significant market potential for growth.
Shanghai Petrochemical’s 12K small tow carbon fiber undergoes polymerization, spinning, and then carbonization with oxygen, resulting in a black and shiny carbon fiber that emerges as a new type of high-strength, high-modulus fiber material with a carbon content of over 95%. It boasts excellent mechanical properties: its density is less than one-fourth that of steel, yet its strength is 7 to 9 times that of steel. It also possesses corrosion resistance and high modulus, which has earned it the title of \"king of new materials\" as well as \"black gold\".
