Major global carbon nanotube producers:
①LG: It already had a production capacity of 500 tons of CNTs in 2017. In April 2021, it announced that its second CNT plant in Yeosu, South Korea, with a 1,200-ton expansion project has been completed and started operation;
②Saudi Basic Industries Corporation (SABIC): In January 2019, it announced the acquisition of a majority stake in the nanotechnology company Black Diamond Structures (BDS). BDS MOLECULAR REBAR technology can produce carbon nanotubes with uniform aspect ratio, clean and discrete distribution, mainly Applied to high-performance energy storage.
③OCSiAl: The company was established in 2009 and is headquartered in Luxembourg. At present, it has an annual production capacity of 90 tons of single-walled carbon nanotubes, accounting for 90% of the global single-arm carbon nanotubes. After the first phase of the new plant in Luxembourg is put into operation in 2024, its production capacity can be increased to 240 tons per year. Its representative products are the single-arm carbon tube products of the TUBALL series.
④Nanocyl SA: Founded in 2002 in Belgium. Focusing on multi-walled carbon nanotubes, its products are widely used in plastics, textiles, rubber and other fields.
