R142B (difluoro monochloroethane) is used as a refrigerant for high-temperature air conditioning, can also be used as a foaming agent, an intermediate in the production of PVDF vinylidene fluoride, temperature controller media and aerospace propellants, and is also used as a chemical raw material.
Refrigeration oil used in R142b
Suniso 4GS, 5GS, Capella WF68, LUNARIA KA56, etc.; what kind of refrigeration oil is ultimately used in different equipment and different application locations, The refrigerator lubricating oil required by the same design and technician should be used in accordance with the recommendations of the refrigerator compressor and refrigeration (air conditioning) equipment manufacturers, or based on the specific conditions of the use of the refrigeration compressor and refrigeration equipment, that is, the equivalent refrigerator oil should be used.R142b Packaging Specifications

Regulatory and compliance status (R142b / Chlorodifluoroethane (HCFC-142b)) — phase-out in progress
R142b (Chlorodifluoroethane (HCFC-142b)) belongs to the hydrochlorofluorocarbons (HCFC), with an ODP of 0.065, and is a Class II controlled substance under the Montreal Protocol, currently subject to the global phase-out schedule. Developed countries halted production and import in 2020; developing countries (including China) are advancing according to the schedule, with servicing stock tightening year by year. The following are the regional status as of 2026.
EU
- RegulationOzone-Depleting Substances Regulation (EC) 1005/2009
- StatusVirgin HCFC no longer placed on the market
- ServicingUse of reclaimed product permitted until 2030 (for some equipment types)
- For R142bNo supply of virgin product; servicing must use reclaimed product and must be performed by certified personnel
US
- RegulationClean Air Act Title VI + SNAP program
- StatusProduction and import of virgin HCFC halted from 2020-01-01
- Existing stockReclaimed product can be used for the maintenance of existing equipment
- For R142bOnly reclaimed product available; supply and prices continue to tighten
China
- RegulationRegulations on the Administration of Ozone-Depleting Substances (2024 revision) + National Phase-out Plan
- Schedule67.5% baseline reduction by 2025, 97.5% by 2030, with only a minimal amount retained for servicing use after 2040
- QuotaAnnual quota licensing for production and use, decreasing year by year
- For R142bSupplied within quota; procurement must be filed; servicing use given priority
- Domestic procurement qualificationMust be filed in the “Ozone-Depleting Substances Information Management System”; suppliers must verify the filing
Japan
- RegulationOzone Layer Protection Act + Act on Rational Use and Proper Management of Fluorocarbons
- StatusHCFC is essentially abolished, with only reclaimed product in circulation
- For R142bNo supply of virgin product; must be retrofitted or replaced
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 R142b: a controlled substance in the phase-out process, with supply tightening year by year and prices rising. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).
