What Alkegen does

Alkegen is a global specialty materials platform formed in 2022 from the merger of Unifrax and Lydall, backed by private equity sponsor Clearlake Capital. The company designs and manufactures fiber-based specialty materials spanning ceramic fibers, glass microfibers, synthetic fibers, aerogel, and refractory products used across filtration, insulation, battery, fire protection, sealing, and geotechnical applications. Its technology stack includes proprietary brands such as Fiberfrax (ceramic fiber invented 1942), SiFAB (silicon fiber anode), Inovion (inorganic fiber battery separator), FyreWrap (passive fire protection and battery thermal runaway barriers), LydAir and LyPore (filtration media), Purefrax (hot gas filters), Thermbond (refractories), Saffil, and AlkeGel (aerogel), with over 100 proprietary formulations and a vertically integrated production chain from raw fiber through finished components. The platform also operates acquired brands Rex Materials Group (vacuum-formed ceramic fiber and fused silica) and Interface Performance Materials (sealing systems).

Alkegen's business model is B2B enterprise hardware sales with quote-based pricing tailored to customer specifications, volumes, and contract terms. Go-to-market combines direct enterprise field sales (engineering and procurement engagement), OEM-embedded supply (materials integrated into automotive battery systems, aerospace components, semiconductor cleanrooms, industrial equipment), and event-driven demand generation at industry trade shows such as The Battery Show, FILTECH, Hillhead, SMM, Aluminium, Fakuka, and Ankiros. The company generates revenue from five primary product categories: Insulation & Thermal Management, Filtration & Catalysis, Battery & Mobility, Fire Protection & Construction Materials, and Sealing & Gasket Solutions, sold to industrial manufacturers, OEMs, and large-scale facility operators.

The company serves 14+ customer segments organized by vertical including petrochemical/ethylene, energy storage systems, aerospace & defense, automotive, medical/life sciences, building & construction, metals (aluminum and non-ferrous), marine & offshore, power generation, ceramics & glass, mining & aggregate, rail & metro, utilities/wastewater, and plastics & injection molding. Notable enterprise customers and partners include JLR (Jaguar Land Rover), ITER (with Air Liquide for cryogenic helium transfer lines), semiconductor cleanroom operators, data center operators, and ethylene furnace operators. Alkegen operates 60+ manufacturing facilities globally with 9,000+ employees, supported by IATF-certified automotive sites in North America, Europe, and Asia-Pacific, and a mobile application providing access to Safety Data Sheets and Product Information Sheets.
