Tedlar films serve as the critical component of photovoltaic backsheets, providing long-term durability and performance for photovoltaic modules in all-weather conditions.

The film line expansion will be located at the DuPont Circleville, Ohio, facility using existing and retrofitted assets. This expansion provides Tedlar oriented film capacity to support global demand of over 10 gigawatts (GW) of photovoltaic module production.

The investment will deliver DuPont technology to help meet increasing needs for energy and environmental sustainability. This reflects the company's recently announced commitment to focus on meeting four emerging global trends, one of which is decreasing dependence on fossil fuels. Film production is scheduled to start up in September 2011.

"The photovoltaic market increasingly demands materials that enable modules to reliably deliver power for decades," said David B. Miller, president - DuPont Electronics and Communications. "This major expansion underscores our commitment to maintaining DuPont leadership in the photovoltaic industry and specifically in the backsheet materials market for solar panels."

The manufacturing steps for Tedlar oriented film include producing vinyl fluoride (VF) monomer, which is converted into polyvinyl fluoride (PVF) polymer resins, and extruded into the Tedlar film. DuPont plans to increase monomer and polymer resin capacity by more than 50 percent. Construction is under way for these new monomer and resin facilities at the DuPont Louisville, Ky., and Fayetteville, N.C., sites, respectively, and the facilities are scheduled to start up in mid-2010.

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 new 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 by 2012.

DuPont Tedlar PVF films have been an essential component of photovoltaic backsheets for more than 25 years. 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. Tedlar films also are used in key applications for aerospace, construction and graphics arts because of their durability and weatherability.

DuPont Tedlar PVF films are part of the broad and growing portfolio of products from DuPont Photovoltaic Solutions, which applies DuPont science and technology to support the dramatic growth of the photovoltaic industry globally.

DuPont - one of the first companies to publicly establish environmental goals 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.
