Producer
Shandong Dongyue Chemical Co., Ltd. (Dongyue Group)
Tangshan Town, Huantai County, Zibo, Shandong, China. Founded 1987; described as "China's renowned largest fluoro-silicon production base." Total HFC refrigerant capacity exceeds 500,000 tonnes/year across product lines. Primary products: HCFC-22 (40,365 MT/yr), HFC-32, HFC-125, HFC-134a, HFC-152a, HFC-142b; also PTFE (polytetrafluoroethylene). R&D focus is on fourth-generation refrigerants (HFO-1234yf, HFO-1234ze, HCFO-1233zd, HFO-1336mzz). HFC-227ea is within the broader product portfolio as one of the fluorocarbon chemicals produced at the Zibo complex; specific fire-grade HFC-227ea capacity not publicly disclosed. Dongyue is publicly listed on the Hong Kong Stock Exchange (0189.HK).

Did you know2023
Dongyue Chemical produces HFC-227ea (the chemical in FM-200 fire suppression systems protecting server rooms and data centers globally) from the same Zibo, Shandong facility that produces HFC refrigerants for air conditioning and HFO-1234yf for automotive AC systems. The same fluorochemical production complex serves three completely distinct markets: commercial building fire suppression (HFC-227ea), HVAC and refrigeration (HFC-32, HFC-134a, HFC blends), and automotive air conditioning (HFC-134a, HFO-1234yf). A US tariff on Chinese fluorochemicals, a Shandong environmental enforcement shutdown, or a Dongyue plant accident would simultaneously affect fire suppression agent supply for data centers and server rooms, commercial refrigeration refrigerant supply, and automotive AC refrigerant supply -- three markets monitored by entirely separate government agencies and industry bodies with no coordinated supply chain visibility.
Shandong Dongyue Chemical Co., Ltd. ↗Origin2023
Dongyue Chemical was founded in 1987 in Tangshan Town, Huantai County, Zibo, Shandong Province -- a location chosen for its proximity to Shandong's chlor-alkali chemical industry (the precursor to HF acid, which is the upstream input for all fluorochemicals). Zibo City is one of China's oldest chemical industrial centers, with chlorine and caustic soda production dating to the early Communist industrial period. Dongyue built its fluorochemical empire on top of this regional chemical infrastructure, scaling from HCFC-22 production (the original refrigerant replacement for CFCs) through HFCs and into fourth-generation HFO refrigerants as successive global phase-down agreements required refrigerant transitions. Dongyue Group is now publicly listed on the Hong Kong Stock Exchange (0189.HK) with total HFC refrigerant capacity exceeding 500,000 tonnes/year -- making it one of the largest fluorochemical producers in the world, from a Shandong county most Western HVAC procurement managers have never heard of.
