PFAS Fluorosurfactant (AFFF Concentrate)

Fire-protection maker (Ansul, Chemguard brands); historically a major AFFF/PFAS-foam producer and a primary PFAS-contamination defendant; now pivoting to fluorine-free foam.

3M Company (Maplewood MN; NYSE: MMM; ~$23B revenue after Health Care spinoff; ~$35B before) is the dominant US manufacturer of N95 respirators and is vertically integrated into meltblown polypropylene nonwoven production. 3M manufactures its own electret (electrostatically charged) meltblown filtration media at its Arden Hills, MN facility — a rare example of vertical integration in nonwovens. 3M's N95 respirators (1860, 8210, 8110S) use proprietary Filtrete electret media. During COVID-19, 3M doubled N95 production to ~2 billion respirators/year (from ~1B) but could not scale meltblown capacity fast enough to meet demand — the Arden Hills facility was the binding constraint. 3M also sells Filtrete HVAC filter media (MERV 11-13) made from the same meltblown technology, generating ~$700M/year in home filtration revenue alongside its respirator business.

Angier, North Carolina-based fire suppression foam manufacturer. Products: Avio F3 Green Mil 3% SFFF MIL-SPEC (launched August 2024). DoD QPL: YES — Avio F3 Green Mil listed August 8, 2024 as the third F3 product on DoD QPL-32725; FAA Part 139 approved concurrently for airport use. National Foam is a private company separate from NAFFCO (National Fire Fighting Manufacturing FZCO, Dubai) — the similar names are coincidental; these are entirely different entities. National Foam's simultaneous FAA Part 139 approval is strategically important as airports must transition away from AFFF on the same timeline as DoD, creating dual-market demand for the same QPL-listed products.

St. Louis, Missouri-based specialty chemical company (NYSE: PRM); SK Capital-owned. The dominant F3 foam producer, formed through acquisitions: Solberg (Green Bay WI, 2018), Auxquimia (Mieres, Asturias Spain, via ICL 2018). Primary F3 products: SOLBERG 3% MIL-SPEC SFFF (first F3 product on DoD QPL, September 2023) and SOLBERG EVOLUTION 3% SFFF (FM 5130 approved March 2026 — first Newtonian F3 foam to achieve FM approval for fixed sprinkler systems). DoD QPL has since expanded to four products (Feb 2024: Bio-Ex ECOPOL; Aug 2024: National Foam Avio F3; Apr 2025: Fomtec Enviro MIL) but Perimeter Solutions remains the most broadly approved. Also produces wildfire retardants (PHOS-CHEK series — the iconic red retardant dropped by aerial tankers) and other specialty firefighting chemicals. Perimeter Solutions simultaneously holds the most critical positions in two converging markets: DoD AFFF replacement AND aviation AFFF replacement (Part 139).

Wilmington, Delaware-based specialty chemicals company (NYSE: CC); spun off from DuPont in 2015. Holds the FM-200 trademark for HFC-227ea (heptafluoropropane, GWP 3,220) clean fire suppression agent. Primary production: El Dorado, Arkansas (322 Southfield Cutoff Road, El Dorado AR 71730) — the key Chemours fluorochemicals plant; produces FM-200, pharmaceutical-grade HFC-227ea, and 1336E; also added HFO production unit at El Dorado in January 2022. Fayetteville, NC is a different Chemours site linked to GenX/PFAS contamination of Cape Fear River. Louisville, KY is linked to HFC-23 emissions controversy. In 2023, Chemours partnered with A-Gas to enable recycled FM-200R (UL-listed, FM-approved) as a response to tightening AIM Act supply limits. The AIM Act imposed 30% additional US HFC production cut in 2024 (on top of 10% in 2023) = 40% total reduction from 2022 levels — directly impacting Chemours' FM-200 output. Also produces Opteon refrigerants and Teflon products. Chemours is the largest Western producer of HFC-227ea by revenue market share.
