R134a HFC Refrigerant

Arkema S.A. (Colombes, France; Euronext: AKE; ~€11B revenue 2023; specialty chemicals and advanced materials) is the world's largest producer of tert-butyl mercaptan (TBM), the primary natural gas odorant compound used across North America and much of Europe. Arkema's Lacq, France facility — located in the historic Lacq natural gas field in the French Pyrenees — is the dominant global TBM production site. Arkema also produces ethyl mercaptan (EM) and other thiol compounds. TBM production at Lacq leverages proximity to historic sulfur byproducts from the local natural gas field; Lacq was France's primary natural gas production region from the 1950s through the 1990s. Arkema also supplies mercaptans for industrial chemical synthesis (pharmaceuticals, rubber additives, lubricant additives) through its Thiochemicals business line. Arkema's broader portfolio includes high-performance polymers (PEBA, PVDF), adhesives (Bostik), and coating solutions (Coatex).

Daikin Industries Ltd. (Osaka Japan; Tokyo: 6367; ~¥4.4T revenue 2023) is the world's largest air conditioning manufacturer and a major manufacturer of refrigeration units for ocean shipping containers (reefer container units) through its Daikin Container division. Daikin's reefer container refrigeration units compete with Carrier Transicold container units in the ocean reefer shipping market. Daikin Container's manufacturing is concentrated in Japan and China. Daikin is also the world's largest producer of fluorocarbon refrigerants and fluoropolymers — the chemical feedstocks for HFC refrigerants including the R-452A and R-448A blends that are replacing R-404A in reefer equipment. This creates a unique dual position: Daikin manufactures the reefer equipment AND the refrigerants that run in it, AND the refrigerants' feedstock chemicals. Daikin's acquisition of Goodman (Australia/US HVAC) and McQuay International (US commercial HVAC) makes it the dominant global HVAC manufacturer alongside Carrier and Trane.

American industrial conglomerate (Nasdaq: HON, HQ Charlotte NC; ~$36B revenue); Performance Materials and Technologies division produces HFA-134a refrigerant and pharmaceutical-grade propellant, as well as next-generation low-GWP alternatives including Solstice® HFO-1234yf (automotive AC replacement) and HFA-152a (low-GWP pMDI propellant for next-generation inhalers). Honeywell is developing pharmaceutical-grade HFA-152a as the primary replacement for HFA-134a in pMDIs as EU F-gas regulations phase down 134a — GWP of 152a is 4 vs 1,430 for 134a, meeting European climate targets. AstraZeneca, GlaxoSmithKline, and other pharma companies are partnering with Honeywell to develop and qualify HFA-152a-propelled inhalers for regulatory submission. Honeywell's position as both an HFA-134a producer AND a leading HFA-152a developer gives it a unique role in the regulatory transition threatening the current pMDI supply chain.

Division of Orbia (formerly Mexichem). World leader in pharmaceutical-grade HFA propellants under the Zephex brand. Zephex 134a in ~75% of global pMDIs. Only FDA-registered active HFA-134a supplier in the US. Opened world's first commercial HFA-152a pharmaceutical manufacturing facility at Runcorn, UK in March 2022.

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.
