Chemours Opteon™ refrigerants are a family of next‑generation cooling fluids designed to deliver high performance with a much lower environmental impact. R‑454B, marketed by Chemours as Opteon™ XL41, is a next‑generation, low‑GWP replacement for new air‑conditioning systems. It offers the lowest global warming potential of any commercially available R‑410A alternative, with a GWP of 466, which is 78% lower than R‑410A’s 2088. 80% of major U.S. HVAC OEMs have selected R‑454B as their replacement for R‑410A.
