Du Pont has announced that it estimates nearly 3 million vehicles worldwide will use HFO-1234yf as a refrigerant by the end of 2014.
Thierry F. J. Vanlancker, president, DuPont Chemicals & Fluoroproducts, said: “The EPA credits alone provide enough incentive to automakers that we expect to see more than 50 per cent of automobiles in the U.S. market converted to HFO-1234yf by 2018.
“Of course, we expect higher conversion in the European market, driven by the need to comply with the MAC Directive.”
HFO-1234yf was specifically developed to enable automakers to comply with the EU MAC Directive, which requires that all new model type cars sold in EU Member States use an automotive refrigerant that has a global warming potential (GWP) of less than 150.
By 2017, all new cars sold in Member States must meet this requirement.
However Mercedes has rejected a switch to the r1234yf alternative which has been brought in under the EU’s MAC Directive, which it claims is potentially flammable – a position denied by the refrigerant producers.
On this subject, Du Pont stated: “While a few voices in Germany continue to raise concerns about this product relative to flammability and potential incineration by-products, these claims have been extensively and thoroughly investigated by third party research initiatives in settings that simulate real-life situations. Based on results of these evaluations, HFO-1234yf has been accepted by the automotive industry and by regulatory bodies.”
