Fumed Silica (AEROSIL) — CMP & Industrial

Evonik Industries AG (XETRA: EVK; Essen Germany; MDAX listed); world's largest DL-methionine producer under the MetAMINO brand. Total DL-methionine capacity exceeds 700,000 MT/year across three continental hubs: Jurong Island Singapore (~340,000 MT/year — world's largest single methionine complex, expanded +40k MT August 2024), Theodore Mobile County Alabama USA (~245,000 MT/year), and Antwerp Belgium (~120,000 MT/year). The Wesseling Germany DL-Met line closed Q1 2021 as Evonik consolidated production to the three-hub network. Evonik first commercialized DL-methionine synthesis in the 1950s under predecessor Degussa. MetAMINO is Evonik's largest single product. ~30-32% global market share. In February 2022 Evonik announced a $176.5M investment in a new methyl mercaptan (MMP intermediate feedstock) plant at the Alabama site.

Second largest fumed silica; Cab-O-Sil brand; Tuscola IL and Hanover Germany plants; semiconductor CMP and electronics applications; also activated carbon (Norit)

Wacker Chemie AG (Munich, Bavaria, Germany; XETRA: WCH; ~€6B revenue; majority-owned by Dr. Alexander Wacker Familiengesellschaft family trust, ~50.3% stake) is the world's second-largest silicone producer with approximately 20-25% global silicone market share. Wacker's BELSIL brand personal care silicones (BELSIL DM dimethicone fluids, BELSIL CM cyclomethicone, BELSIL PDM dimethicone copolymers) are major ingredients in hair conditioners, shampoos, and skin lotions globally. Wacker's Burghausen, Bavaria facility is the world's largest single integrated silicone production site — a 500-hectare campus on the Salzach River employing ~6,000 people where Wacker produces silicon metal, methylchlorosilanes, silicone polymers, and downstream personal care silicone grades within a single Verbund complex. The same Burghausen campus also produces hyperpure polysilicon for solar panels and semiconductors — Wacker Polysilicon is the world's second-largest polysilicon producer. Wacker's second major silicone site is Nünchritz, Saxony (formerly East Germany), which produces silicone intermediates and specialty grades. In 2024, Wacker announced restructuring including headcount reductions driven by Chinese silicone competition and solar market pricing pressure.

Japanese specialty chemicals; fumed silica and polysilicon; Tokuyama Yamaguchi Japan primary plant; strong in semiconductor applications in Asian fab cluster

South Korean chemicals company (unrelated to OCI NV / Fertiglobe). Operates an integrated polysilicon and chlorosilanes plant at Gunsan and Iksan, Korea, producing solar-grade and semiconductor-grade silicon tetrachloride as co-product of polysilicon production. One of four non-Chinese producers capable of fiber-optic and semiconductor-qualified SiCl4.

Ukrainian fumed silica producer (Kalush Ivano-Frankivsk); significant European fumed silica source; operations impacted by Russian invasion 2022; produces aerosil for chemical and coatings applications
