WILMINGTON, Del., April 24, 2013 (GLOBE NEWSWIRE) -- via PRWEB - DuPont
announced today that it continues to make strong progress in commercializing
Opteon™ YF (HFO-1234yf) refrigerant and that a group of leading automakers
confirms that the product is "safe and effective." Opteon™ YF is a scientific
breakthrough that has a 99.7 percent lower global warming potential (GWP) than
the refrigerant it was developed to replace, and has potential to reduce
emissions equivalent to using billions fewer liters of fuel every year.

DuPont is making commercial shipments of Opteon™ YF from facilities in both
Japan and China. The manufacturing scale-up of Opteon™ YF to date has been
accomplished in an unprecedented time frame. The product is in use by
automakers around the world.

A consortium of 10 European, North American and Asian automakers has announced
this week that it has carefully evaluated extensive testing conducted by its
members with HFO-1234yf, including additional testing to study potential
ignition of the refrigerant in a crash. The group states that it has now
updated its risk assessment and that HFO-1234yf refrigerant "is safe and
effective to use in automotive applications" and "the risk of passenger
exposure to a vehicle fire associated with this refrigerant is exceptionally

The team of automakers also stated that the refrigerant release testing
conducted by Daimler "did not include any actual vehicle collisions or the
mitigating factors that occur in an actual collision" and the refrigerant
release apparatus and nozzle used in the testing "does not represent actual
crash damaged refrigerant lines, and was found to be artificial." This team
stated that it has followed a risk assessment approach that has been
recommended and used by numerous public and private organizations, including
the European Union Joint Research Centre and the U.S. Environmental Protection
Agency. For more information visit:

"DuPont has a high level of confidence that Opteon™ YF can be safely used in
vehicle air conditioning and we know that it delivers a wide range of other
benefits to automakers, consumers and society," said Thierry F. J. Vanlancker,
president, DuPont Chemicals & Fluoroproducts. "We continue to focus our
attention on delivering this product to our automotive customers around the
world for use in their latest new car model introductions."

DuPont forecasts indicate that the company has enough supply to meet current
customer needs for compliance with the European Union's Mobile Air
Conditioning (MAC) Directive. DuPont is prepared to invest in additional
capacity to support increasing customer adoption around the world. In
addition, the company has established a strong network for distribution of
Opteon™ YF to aftermarket customers in Europe.

The MAC Directive has been in force since Jan. 1, 2013, and must be respected
throughout the European Union, according to Antonio Tajani, vice president of
the European Commission, in his March 20, 2013, comments to the EU Parliament
Environmental Committee.

"Automakers from around the world have placed orders for Opteon™ YF and are
working to comply with the MAC Directive," said Vanlancker. "This regulation
is an essential component in the European Union's sustainability programs and
will have significant impact on reducing the environmental footprint of

DuPont co-developed HFO-1234yf in response to Europe's MAC Directive, and the
company markets and sells the refrigerant under the name Opteon™ YF. DuPont
applies its scientific expertise to creating sustainable solutions that make a
difference in the world and commercialization of Opteon™ YF is a great example
of this commitment.

The China facility that supplies DuPont with Opteon™ YF has consistently met
or exceeded its targets for supply reliability, production levels and product
quality. Automakers that have transitioned to Opteon™ YF, or are preparing to
make this transition, are scheduling visits to the facility in China to
understand its capabilities and quality assurance processes.

DuPont – one of the first companies to publicly establish environmental goals
more than 20 years ago – has broadened its sustainability commitments beyond
internal footprint reduction to include market-driven targets for both revenue
and research and development investment. The goals are tied directly to
business growth, specifically to the development of safer and environmentally
improved new products for key global markets.

DuPont (NYSE:DD) has been bringing world-class science and engineering to the
global marketplace in the form of innovative products, materials, and services
since 1802. The company believes that by collaborating with customers,
governments, NGOs, and thought leaders we can help find solutions to such
global challenges as providing enough healthy food for people everywhere,
