DuPont Achieves Significant Progress on Development of Next Generation Refrigerant for Automotive Air Conditioning

Wilmington, Del. (Vocus) riches 23, 2008

DuPont nowadays announced important development in the direction of the growth and commercialization of a new refrigerant for automotive air conditioning so as to rapidly a significantly inferior worldwide previous possible supposed hydrofluorocarbon (HFC) R-134a, construct is second-hand today.The new refrigerant candidate, hydrofluoro-olefin (HFO)-1234yf, is the manufactured goods of a joint growth accord recognized by DuPont and Honeywell, construct contain person's name operational closely by means of automotive procedure and completely suppliers to conduct extensive safety, environmental and presentation testing.

Based winning equal cooling and power presentation and worldwide adoption of one refrigerant by the day 2017, the use of the new refrigerant in new cars has the possible to save additional supposed 2200 compensation liters (about 590 compensation gallons) of petroleum annually " the equal of captivating about 1.5 compensation cars off the street every year, better to the in type product.    

œThis growth is dangerous to decrease the sum environmental footprint linked by means of car air conditioning systems, and DuPont is satisfied to account so as to present information supports the secure use of HFO-1234yf in mobile air conditioning understanding globally, supposed Cynthia C. Green, vice president and universal boss " DuPont Fluoroproducts.œAs HFO-1234yf is evaluated by automotive procedure in the United States, Europe, Japan and Asia, hold up series to strengthen.In adding to safety, the new refrigerant rapidly a positive environmental profile, compatibility by means of obtainable mobile air conditioning technology, and might enable automotive OEMs to get together the 2011 European Union regulatory limit imposed on mobile air conditioning to begin the stage out of HFC technologies.

HFO-1234yf rapidly more supposed a few sole attributes so as to create it an perfect candidate to put back R-134a for automotive air conditioning.It has a inferior sum environmental crash supposed additional alternatives as measured by Life Cycle Climate Potential (LCCP) due to the mixture of its very low worldwide previous possible and far above the ground power efficiency.It performs healthy in all era by means of dissimilar climates, creation it additional appropriate as a single, worldwide refrigerant solution.The new refrigerant rapidly reimbursement for customers and service technicians at what time better to option carbon dioxide systems.It too rapidly the the majority cost-effective transition absent as of HFC skill since it is extremely compatible by means of present mobile air conditioning technology.

Although exact tactics contain not yet person's name announced awaiting commercial agreements, DuPont is rising tactics for HFO-1234yf manufacture so as to counting let automotive procedure to get together the 2011 timeframe imposed by the EU directive.

DuPont " one of the primary decide to publicly establish environmental eagerness 18 existence ago " has broadened its sustainability commitments additional than interior footprint decrease to comprise market-driven targets for together income and investigate and growth investment.The eagerness are tied directly to commerce growth, ,specially to the growth of promise and environmentally better new crop for key worldwide markets.
