News	September 3, 2024 - NES Materials, a subsidiary of Namhae Chemical, has begun supplying Samsung with high-purity sulfuric acid (H2SO4) since last month, TheElec has learned. The material is used in cleaning processes during chip production. NES Materials was formed in 2021 and is a joint venture of Namhae Chemical, ENF, and Samsung C&T, each owning 70%, 20%, and 10% of the company. Namhae Chemical operates the factory and procures the raw material; ENF verifies quality; and Samsung C&T connects the company with buyers. NES Materials began constructing the high-purity sulfuric acid factory in May 2022 and completed it last year. The factory has a capacity of 54,000 metric tonnes per year and uses the SO3 by-product from Namhae Chemical’s fertilizer production to produce the acid. Samsung is procuring the acid from NES Materials earlier than expected as a competitor of the chemical firm has faced production issues, sources said. The South Korean tech giant wants to diversify its supply chain for the material, which means NES Materials’ supply of the chipmaker is expected to steadily increase, they said. Other South Korean producers of the acid include Korea Zinc and LSMnM. A Namhae Chemical spokesperson has confirmed that NES Materials has begun supplying the acid to a customer. Namhae Chemical is also preparing new materials that are used in tech production besides sulfuric acid, the sources also said. July 23, 2024 - Namhae Chemical’s subsidiary NES Materials has supplied a prototype high-purity sulfuric acid to Samsung for use in chip production. H₂SO₄, which used to clean wafers, is going through a performance test by the South Korean tech giant, sources said. NES Materials is a joint venture formed in 2021 by Namhae Chemical, ENF Technology, and Samsung C&T, each owning stakes of 70%, 20%, and 10%, respectively. The venture began constructing the sulfuric acid factory in May 2022 and completed last year. The factory has a capacity of 54,000 metric tonnes per year, or 18% of the total output in South Korea for high-purity sulfuric acid. NES Materials uses SO₃ by-product made when Namhae Chemical produces in fertilizer for the sulfuric acid production. A Namhae Chemical spokesperson confirmed that it has produced a prototype sulfuric acid and provided into a customer but didn’t name Samsung. Commercial production is expected start late this year or next year, they added. Namhae Chemical is expected to compete with Korea Zinc, LSMnM, and Dongwoo Finechem for orders. Korea Zinc is the largest producer of sulfuric acid among these companies. September 17, 2002 - South Korean fertiliser and speciality chemicals producer Namhae Chemical Corp has been officially split into two entities, a company spokesman told CNIon Tuesday. Namhae has retained the fertilisers business while the base and fine chemicals business has been transferred to a new company - Human Chemical Sciences Co (Huchems). Namhae, in its new form, and Huchems will be listed on the Korean Stock Exchange on 7 October. Shareholders agreed last month to divide the company into two focussed entities in order to increase stock value. Namhae will retain 600 employees whilst transferring 230 staff members to Huchems. Namhae’s fertilisers business has been hit by poor markets, whereas its speciality chemicals business has been performing well. The fertiliser division currently accounts for about 70% of the company's total annual sales, while the chemical division accounts for the rest. Namhae operates two lines of compound fertilisers at Yeochun, South Korea, with a combined production capacity of 1.3m tonne/year. It closed a 660 000 tonne/year urea plant and a 600 000 tonne/year ammonia plant in Yeochun this February. Huchems will produce basic chemicals such as ammonia, sulphuric acid, phosphoric acid, carbon dioxide, gypsum, argon, and potassium chloride. Its fine chemicals include dinitrotoluene (DNT), mononitrotoluene (MNT), toluidine, melamine, ammonium nitrate and nitric acid.
