R1270 is a natural refrigerant with the advantages of large cooling capacity and high COP. Environmental protection performance (ozone depletion potential value is 0, greenhouse effect potential value is low) and basic thermophysical properties are good (cooling capacity per unit mass and cooling capacity per unit volume are greater than R22, exhaust temperature is lower than R22, latent heat of vaporization and thermal conductivity are both greater than R22), and some basic thermophysical properties (saturated vapor pressure) are similar to R22. It has excellent thermodynamic properties and good system cycle performance, and is a promising pure substitute for R22. Under the same conditions, the system refrigeration capacity of R1270 and R22 is basically the same. Compared with the R22 refrigeration system, the energy efficiency ratio of R1270 is increased by 6.5%, the charge capacity is reduced by 51%, and the compression ratio is reduced by 27%. On the premise of meeting the refrigeration capacity, by optimizing the evaporator, changing the diameter of the evaporator from 7mm to 5mm, reducing the number of U-shaped tubes, and changing the flow path layout, an R1270 prototype test with only changing the evaporator was carried out. The results show that the refrigeration capacity of the R1270 and R22 systems is basically the same. The energy efficiency ratio of the R1270 refrigeration system is 3.31. Compared with the R22 refrigeration system, the energy efficiency ratio is increased by 12.6%, and the charge capacity is reduced by 55%.

Regulatory and compliance status (R1270 / Propylene)
R1270 (Propylene) has an ODP of 0 and a GWP of only about 2; it is neither an ozone-depleting substance nor a hydrofluorocarbon (HFC) subject to reduction under the Kigali Amendment. As a natural hydrocarbon refrigerant, it is instead encouraged for use as a low-GWP alternative by major economies. The following are the regional status as of 2026.
EU
- RegulationF-gas Regulation (EU) 2024/573, in force since 2024-03-11
- ClassificationThis regulation targets HFC; R1270 is a natural refrigerant and is outside the reduction scope
- Policy directionPromoted as a low-GWP alternative (one of the preferred alternatives for domestic/commercial refrigeration)
- For R1270GWP 2, not affected by the GWP>150 new-equipment ban; can be used in new installations
US
- RegulationAmerican Innovation and Manufacturing (AIM) Act (in force since 2020-12-27) + SNAP
- ClassificationConstrained object is HFC; R1270 is non-HFC
- Policy directionSNAP lists hydrocarbons as acceptable low-GWP alternatives (with charge limits)
- For R1270Not bound by the AIM Act HFC quota
China
- RegulationKigali Amendment (entered into force for China on 2021-09-15)
- ClassificationReduction target is HFC; R1270 is a non-HFC natural refrigerant
- Policy directionEnergy-efficiency and environmental policies encourage the adoption of low-GWP refrigeration solutions
- For R1270Not bound by HFC quota; its use is encouraged
- Domestic procurement qualificationNon-HFC, outside the scope of this filing; still must comply with A3 flammable refrigerant safety/transport qualifications
Japan
- RegulationAct on Rational Use and Proper Management of Fluorocarbons
- MechanismSets caps by “weighted-average GWP” for designated products (domestic ≤750, commercial ≤750, automotive ≤150, condensing ≤1500, cold storage ≤100)
- For R1270GWP 2 is far below the caps of all equipment types; fully usable in new equipment and encouraged as a low-GWP alternative
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 R1270: not affected by HFC reduction. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).
Buyer conclusion: R1270 is a hydrocarbon natural refrigerant with GWP≈2 and ODP 0 and is not an HFC reduction target; the EU, US, Japan and China all encourage its use as a low-GWP alternative, with no ban risk and instead favourable treatment under environmental compliance policies. It is suitable for new projects with high GWP/ODP compliance requirements (domestic/commercial refrigeration, freezers, etc.). Note: R1270 is a A3 flammable refrigerant; system design, charge quantity and installation must comply with explosion-protection and ventilation standards such as EN 378 / IEC 60335-2-89, and verify lubricant compatibility. Domestic procurement has no HFC environmental filing threshold (but must meet A3 flammable refrigerant safety/transport qualifications).

R1270 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.
R1270 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.
