FAYETTEVILLE, N.C., Aug. 25, 2010 – Underscoring its ongoing commitment to developing and delivering cleaner, more efficient energy solutions, DuPont announced that production of polyvinyl fluoride (PVF) polymer resin, a critical raw material used to make high-performance DuPont™ Tedlar® polyvinyl fluoride film, has begun at the DuPont Fayetteville Works facility.  Tedlar® films serve as the essential component of photovoltaic backsheets, providing long-term durability and performance for solar modules in all-weather conditions. 

Production startup at Fayetteville is part of the previously announced multi-phase $295 million investment by DuPont to more than double Tedlar® film capacity for the fast-growing photovoltaic industry.  With increased production for the PVF resins at Fayetteville now under way, additional Tedlar® film production is expected to start up at Circleville, Ohio, in September 2011.

“Starting up the new polymer resin production for Tedlar® film is a critical step necessary for us to meet the overwhelming customer demand for this essential solar panel backsheet material,” said David B. Miller , president – DuPont Electronics & Communications.  “Tedlar® enables solar panels to deliver reliable power output for 25 plus years.  This capacity expansion will allow us to help our customers supply the highest quality solar modules as the market continues to grow.”

DuPont anticipates that the photovoltaic market will grow rapidly over the next several years, and this growth will drive the demand for Tedlar® and other key materials that increase the lifetime and efficiency of solar cells and modules.  DuPont expects that overall sales of its family of products into the photovoltaic industry will exceed $1 billion in 2011 and $2 billion by 2014. 

DuPont™ Tedlar® PVF films have been an essential component of photovoltaic backsheets for more than 25 years.  The manufacturing steps in making Tedlar® film include producing vinyl fluoride monomer, which is converted into polyvinyl fluoride polymer resins, and extruded to make Tedlar® film.  Tedlar® is widely recognized as the industry standard due to its excellent strength, weather resistance, ultraviolet resistance and moisture barrier properties.  As a result, Tedlar® enables solar modules to achieve long-life performance providing a long-term sustainable energy source for the marketplace.  This results in improved economic returns for investments in solar energy projects and therefore a lower cost of solar electricity to consumers. 

DuPont™ Tedlar® polyvinyl fluoride films are part of the broad and growing portfolio of products represented by DuPont Photovoltaic Solutions, which connects science and technology from across the company on a global scale to help support the dramatic growth of the photovoltaic industry.  To learn more about DuPont Photovoltaic Solutions, visit
