Producer
Chemours
U.S. specialty chemicals company (NYSE: CC, HQ Wilmington DE); spun off from DuPont in 2015, inheriting DuPont's century-old fluorochemicals business that invented Freon (CFCs) in 1930. Now the world's largest HFO refrigerant producer under the Opteon™ brand. Operates world's largest HFO facility in Ingleside, Texas (near Corpus Christi): $300M investment opened June 2019, >3x capacity; expanded further in 2022. Jointly holds patents on R-1234yf (automotive AC) and R-454B (Opteon XL41, HVAC) with Honeywell. R-454B became mandatory for new U.S. HVAC equipment from January 1, 2025 (EPA AIM Act), triggering an active supply shortage with 4-8 week lead times and cylinder prices rising from $345 (2021) to $2,000+ (2025).

USTexas · manufacturing
World's largest HFO (hydrofluoroolefin) refrigerant production facility near Corpus Christi, Texas; $300M investment, opened June 2019, capacity more than tripled at opening; expanded again in 2022. Produces R-1234yf (automotive AC) and R-454B (Opteon XL41, HVAC). ~250 employees + 100 contractors. Manufacturing refrigerants in Coastal Bend area since 1972. This single Texas facility is the primary domestic U.S. source for the mandatory new HVAC refrigerant (R-454B) that took effect January 2025.

Did you know2023
Chemours is simultaneously the world's largest HFO refrigerant manufacturer (Opteon brand for air conditioning) AND the world's largest titanium dioxide (TiO2) producer (Ti-Pure brand). TiO2 is the white pigment in virtually every white or light-colored paint sold globally — Sherwin-Williams, Benjamin Moore, and AkzoNobel all use Chemours Ti-Pure as a primary TiO2 source. TiO2 also appears in sunscreen (mineral UV filter), printer paper coating, and white plastic packaging. The same NYSE-listed chemical company in Wilmington, Delaware that supplies the refrigerant making your home cool in summer also supplies the white pigment coating your home's exterior walls — two completely unrelated $20B+ end markets from the same chemical company's production.
The Chemours Company ↗Incident2024
Chemours announced in 2024 that it would voluntarily stop US sales of Freon™ 404A and 507A — the dominant cold storage HFC refrigerants — ahead of regulatory deadlines. This leaves the North American market dependent on Honeywell Solstice® HFO transition refrigerants and Chinese imports for legacy systems that cannot immediately switch.
The Chemours Company ↗Capacity2023
The US EPA AIM Act R-454B mandate (effective January 1, 2025 for new HVAC equipment) creates an enormous near-term supply constraint with only two companies globally holding key patents on R-454B and R-1234yf: Chemours and Honeywell. The Chemours-Honeywell HFO patent cross-licensing agreement creates a practical duopoly: any company making R-454B needs both companies' patent licenses. Cylinder prices for R-454B rose from ~$345 (2021) to $2,000+ (2025) as the mandate took effect and supply could not scale fast enough. US HVAC system manufacturers and contractors faced lead times of 4-8+ weeks for R-454B refrigerant. This patent-enforced duopoly on mandated-by-law refrigerants gives Chemours and Honeywell pricing power unprecedented in the commodity chemicals industry — regulated mandates combined with patent exclusivity create a textbook coercive pricing situation for a product essential to climate goals.
US Environmental Protection Agency ↗Origin2023
Chemours Company was spun off from DuPont de Nemours in July 2015, inheriting DuPont's entire fluoroproducts, titanium dioxide, and performance chemicals businesses — and critically, DuPont's PFAS (PFOA/C8) contamination liabilities from its Teflon manufacturing and AFFF foam chemical supply history. DuPont's fluorochemistry heritage traces to 1930, when DuPont chemists Thomas Midgley Jr. and Charles Kettering developed Freon (CFC refrigerants) under a GM/DuPont collaboration. Freon solved the refrigerant safety problem of the era (prior refrigerants — ammonia, sulfur dioxide, methyl chloride — were toxic and flammable) but inadvertently created the ozone layer depletion crisis documented in the 1970s-1980s. The corporate lineage that brought the world CFC refrigerants (causing the ozone hole) now makes HFO refrigerants (the replacement that doesn't) — both under a Delaware company that traces to the same 1930 Freon invention.
