Next generation refrigerant options for the future and beyond

Arkema is developing low-GWP (Global Warming Potential) next generation refrigerant solutions to meet the future needs of the industry.

Working with industry leaders, leading OEMs, and customers, Arkema's next generation developmental solutions offer a balance of performance benefits and reduced environmental impact. Long-term, Arkema's global refrigerant solutions will involve movement to very-low GWP refrigerants across all refrigeration and HVAC markets. These and other advances in developmental refrigerant technology highlight Arkema's continuing commitment to developing sustainable and efficient next generation refrigerant options for the future and beyond.


Air conditioning

Forane® R-32

Forane® R-32 has a unique balance of cost, performance, low GWP, and availability, making it a growing choice for HVAC. Forane® R-32 (HFC-32 or R-32) is one of the next-generation low GWP (675) solutions being implemented globally. R-32 is a refrigerant gas for air conditioning, with high capacity and zero glide. Forane® R-32 is growing in consensus as the top choice for new air conditioning units, designed for mildly flammable refrigerants as a replacement for R-410A (GWP 2088).



  • Average molecular weight (g/mol) 52
  • Normal boiling point (°F) -61
  • Critical temperature (°F) 172.6
  • ASHRAE Safety Group classification A2L
  • Ozone depletion potential (ODP) 0
  • Global warming potential (GWP) AR4 675

Forane® HTS 1233zd

Forane® HTS 1233zd is a sustainable choice for chillers, with high efficiency, ultra-low GWP, and non-ODS. Safe to use, R-1233zd is non-flammable, has the lowest toxicity level, is low pressure and versatility. Forane® HTS 1233zd is usable with Mineral Oil, POE, or PVE.




Forane® R-516A

A Forane® R-134a replacement designed to drive to very low GWP with existing equipment designs

Forane® R-516A is a very close match to R-134a properties, azeotropic composition (zero glide), and mildly flammable (A2L).  It is a long-term solution as it has a very Low-GWP (< 150).  Forane® 516A has good compatibility with existing system components for R-134a or R-1234yf.  In screw chiller evaluation, Forane® 516A demonstrated similar performance in the existing technology as well as design compatibility. It has potential for use in existing R-134a equipment with little to or no change.  Forane® 516A is the only long-term solution to maintain a similar footprint to R-134a screw chillers.
