DuPont & HoneyWell Preparing for the Rise of 1234YF

1234YF‘s time has finally come. In 2014 an estimated three million cars on the road are now taking 1234YF refrigerant. In 2015 that number is predicted to climb to seven million. All but one auto manufacturer have switched over from R-134a. R134a has not been banned in the United States, but it’s only a mater of time. It has already been phased out by the European Union  and the United States Government has already announced plans to eventually phase out the HFC refrigerant.The days of the 134a in the United States are numbered.

134a is being phased out due to the high global warming potential that it contains. Global warming potential is measured by  how much heat a greenhouse gas traps in the atmosphere. R-134a’s GWP is measured at over 1,000. It’s replacement, 1234YF, has a global warming potential of less than 1. Quite the difference here, as you can see. If everyone in the world switched over to 1234YF in the next five years there would be a signficant impact on the environment. (In a good way!)

Most everybody agrees that 1234YF is a safe alternative to the environmentally damaging 134. Daimler out of Germany is the only company that I am aware of that is fighting the change. You can read more about Global Warming Potential by clicking here.


DuPont Refrigerant

DuPont’s private brand of 1234YF is known as Opteon YF. DuPont has been expecting the increased demand of this low GWP refrigerant and has begun taking steps to increase production and to be able to keep pace with global demand.

Kathryn K. McCord, global business director of DuPont, was quoted as saying:

“DuPont is prepared to supply HFO-1234yf, which it sells as DuPont™ Opteon® YF refrigerant, to both automakers and the service industry in the United States and Europe. DuPont was the first company to establish capacity of HFO-1234yf, with sites in China and Japan, and capacity expansions we announced last October are on track.  We have sufficient supply to meet our customers’ projected demand, and are prepared to make additional investments when long-term demand justifies it.” As well as, “An extensive distribution network and the availability of equipment enable automakers to adopt this product to comply with the MAC Directive in Europe and to take advantage of greenhouse gas credits in the United States. The industry is moving decidedly toward HFO-1234yf because it offers a range of advantages, including cooling power, energy efficiency, safety, materials compatibility, sustainability and total systems cost effectiveness.”

HoneyWell’s private brand on 1234YF is known as Solstice. Just as DuPont is gearing up production on 1234YF Honeywell announced this week that they have begun full scale production on their Solstice brand of 1234YF. In the fall of 2014 Honeywell was one of the companies that committed to the United States government that they would increase their production of low global warming potential refrigerants and that they would commit to a fifty percent drop in production of high global warming potential refrigerants such as 134a, 410a, and 404a.


It seems that 1234YF will be the go to refrigerant for automobiles for 2015 and for future years to come… that is until they find something wrong with this one as well!
