The Chinese name of R245fa is pentafluoropropane. It is a colorless, transparent and free-flowing liquid. It is volatile. It has a boiling point of 15.3℃. It is stable at room temperature and pressure. It can be used as polyurethane insulation material for refrigerators and boards.blowing agent。asrefrigerantIt is widely used in organic Rankine cycle systems (ORC) and is widely used in low-temperature waste heat (flue gas waste heat, industrial gases, high-temperature fluids, etc.), solar energy, biomass energy, geothermal energy industry, ocean temperature difference and other power generation systems. Using the Machine-Rankine cycle system can increase the amount of clean energy while reducing the amount of clean energycarbon dioxideEmissions. Using R245fa as the working fluid can effectively improve the efficiency of the organic Rankine cycle system by 5%-8%.

Regulatory and compliance status (R245fa / Pentafluoropropane (HFC-245fa))
R245fa (Pentafluoropropane (HFC-245fa)) 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 1030), 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.
EU
- RegulationF-gas Regulation (EU) 2024/573, in force since 2024-03-11
- HFC quota60% in 2025–28, 30% in 2029–33, 20% in 2034–35, 15% from 2036; HFC fully phased out by 2050
- New equipment restrictionsNew refrigeration/air-conditioning equipment with GWP>150 has been banned for sale in phases since 2022 (commercial refrigeration 2022, standalone equipment 2025, fully by 2030)
- For R245faGWP 1030 > 150 — not permitted for new equipment of this type in the EU; servicing or top-up of existing equipment is unaffected
US
- RegulationAmerican Innovation and Manufacturing (AIM) Act (in force since 2020-12-27)
- TargetHFC production and consumption reduced by 85% by 2036
- Quota cap60% in 2024–28, 30% in 2029–33, 20% in 2034–35, 15% from 2036
- For R245faRegulated HFC, exchange value accounted by GWP 1030
China
- RegulationKigali Amendment (entered into force for China on 2021-09-15)
- Baseline2024 production/consumption freeze (production 18.53 billion tCO₂e, consumption 9.05 billion tCO₂e)
- Reduction10% reduction by 2029, 30% by 2035, 50% by 2040, 80% by 2045
- For R245faProduction and use are subject to quota management
- Domestic procurement qualificationHFC-class refrigerants require environmental filing; see the Q&A below (system: new-ods.ozone.org.cn)
Japan
- RegulationAct on Rational Use and Proper Management of Fluorocarbons
- MechanismSets caps based on “weighted-average GWP” for designated products + compliance deadlines (not an all-sector ban)
- Typical capsDomestic air conditioning ≤750 (2018), commercial air conditioning ≤750 (2020), automotive air conditioning ≤150 (2023), condensing/freezing units ≤1500 (2025), cold storage ≤100 (2019)
- For R245faGWP 1030 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 R245fa: 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).
