R236ea is commonly used as a refrigerant and fire extinguishing agent and is a promising long-term alternativeR11、R123andR114A more suitable alternative. Its ODP value is 0 and its atmospheric lifetime is 7.8 years. The U.S. EPA and the U.S. Navy conducted a study on the thermal properties and environmental impact characteristics of 11 working fluids and found that R236ea is the closest to R114. Although R236ea reacts slightly slowly with seven commonly used rubber and plastic materials, the results are still acceptable; The compatibility of HFC236ea with POE-type refrigeration oils within-35℃ to 125℃ is also acceptable.

Regulatory and compliance status (R236ea / Hexafluoropropane (HFC-236ea))
R236ea (Hexafluoropropane (HFC-236ea)) has an ODP of 0 and is not an ozone-depleting substance, and therefore is not bound by the Montreal Protocol phase-out schedule; but as a fluorinated greenhouse gas (F-gas, GWP 1370), it is controlled under the Kigali Amendment and the HFC reduction policies of major economies. The following are the regional status as of 2026, for reference in procurement and compliance decisions.

- For R236eaGWP 1370 exceeds residential air conditioners (≤750), commercial air conditioners (≤750), vehicle air conditioners (≤150), cold stores (≤100) — such new equipment must switch to a lower-GWP refrigerant
Other countries and regions (grouped by the Kigali Amendment)
Apart from the four columns of EU / US / China / Japan, the global 170+ Kigali parties all comply under the A5 (developing countries) / non-A5 (developed countries) groupings of the Montreal Protocol, and none impose equipment-level bans. The grouping determines the HFC reduction pace and is unrelated to geography — for example, the Middle East Gulf and India belong to A5 Group 2, while Brazil, Mexico and Chile belong to A5 Group 1 (same group as China). The table below is a quick reference for the groupings of major markets:
| Grouping | HFC reduction pace | Major countries / regions (representative) |
|---|---|---|
| A5 Group 1 (developing countries, including China) | 2024 freeze → 10% reduction by 2029 → 30% by 2035 → 50% by 2040 → 80% by 2045 | Brazil, Argentina, Chile, Colombia, Peru, Mexico, South Africa, South Korea, Thailand, Indonesia, Malaysia, Vietnam, Egypt, Nigeria, etc. (about 140 countries in total) |
| A5 Group 2 (high-ambient-temperature group, HAT) | 2028 freeze → 10% reduction by 2032 → 20% by 2037 → 30% by 2042 → 85% by 2047 | India, Bahrain, Iran, Iraq, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia, United Arab Emirates |
| Other non-A5 (developed countries, except EU/US/Japan) | 85% reduction by 2036 / reduced to 15% by 2050 | Canada, Australia, New Zealand, Switzerland, Norway, United Kingdom, Russia* (first two steps delayed: 5% by 2020, 35% by 2025), etc. |
For R236ea: subject to quota constraints, long-term supply restricted and prices trending upward. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).

Buyer conclusion: R236ea is still legally produced, sold and used worldwide and is not subject to a comprehensive ban; but as a fluorinated greenhouse gas (GWP 1370), its supply is constrained by national quotas and prices trend upward in the long term. In the EU, new equipment with GWP>150 has been banned in stages; GWP 1370 exceeds that threshold, so it is not permitted for such new equipment; The US and China are also progressively reducing HFCs according to their own schedules; Japan promotes substitution for domestic/commercial/automotive air conditioning based on GWP caps. Recommendation: for new projects, prioritise evaluating low-GWP alternatives (R32, R454B, R513A or a hydrocarbon refrigerant); existing equipment can continue to be maintained with R236ea. Domestic customers must complete environmental filing (“Ozone-Depleting Substances Information Management System”) before purchasing, and suppliers must verify the filing and may not sell to individuals or enterprises not filed as required.

常见问题
R236EA Refrigerant is a refrigerant/chemical product. It is widely used in refrigeration equipment such as refrigerators, freezers, water dispensers, automotive air conditioners, central air conditioning, dehumidifiers, cold storage and commercial refrigeration, as well as in aerosol propellants, blowing agents, fire-extinguishing and cleaning applications. See the product page for details.
R236EA Refrigerant is used as a common working fluid in refrigeration, air-conditioning and industrial applications. When replacing or retrofitting a system, qualified personnel should perform the work, paying attention to system compatibility and lubricant matching, and following relevant safety standards.
Store in a cool, dry, well-ventilated warehouse away from fire, heat sources and direct sunlight. Cylinders should be placed upright and protected from falling. Transport according to regulations for high-pressure gases or hazardous chemicals, with careful handling to avoid damage to cylinders and valves.
Ensure adequate ventilation at the workplace. Avoid direct skin contact with liquid refrigerant (risk of frostbite). Keep away from open flames and high heat. Use dedicated tools and protective equipment. In case of leakage, evacuate, ventilate and contact professionals.
The exact Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are listed in the Physical Properties table on the product page. Select refrigerants considering energy efficiency, safety and environmental impact.
Multiple package sizes are available (e.g., cylinders, drum or ton packages - see product page). Bulk orders are supported. Contact sales for the latest quote and lead time.
