DuPont says Daimler announcement is ‘not new information’
Diane Iuliano Picho, global business manager, Opteon refrigerants, said: “We met with Daimler to understand their testing approach and results, and based on these discussions, DuPont has concluded the testing does not represent new information.”
“It is well known that HFO 1234yf is a mildly flammable refrigerant. Extensive flammability testing was completed by independent globally recognized third-party laboratories. Multiple risk assessments by industry stakeholders, including Daimler, have thoroughly evaluated the product’s flammability, and have shown that there is no significant additional risk for HFO 1234yf versus the current refrigerant.”
Dupont identifies a recent presentation at the European Automotive Air-Conditioning Convention, co-authored by Daimler and presented by the German automakers association (VDA) on Sept. 17, 2012, in Frankfurt, Germany, which concluded that HFO 1234yf equipped vehicles are as safe as those using R134a – for occupants, mechanics, first emergency responders and fire fighters.
Miss Picho added: “DuPont has offered to provide technical expertise to work with Daimler and other automotive OEMs to resolve questions about the adoption of HFO-1234yf as a more sustainable automotive refrigerant, in time to meet the requirements of the MAC Directive by January 1, 2013.”
