WILMINGTON, Del., June 26, 2008 – DuPont Glass Laminating Solutions today announced a price increase of up to 30 percent on all grades of DuPontTM Butacite® polyvinyl butyral interlayer product line effective August 1.

The price increase will be applied globally, while specifics will vary by region. DuPont Glass Laminating Solutions said that this action is required due to the rapid and unprecedented increases in petrochemical feedstock, energy, freight and distribution costs. “Previous price were intended to compensate for increases in these costs; however, they have continued to dramatically increase. The need for immediate structural improvement is unprecedented and necessary to offset margin loss from the higher costs as well as to support continued investment in growing PVB market applications such as photovoltaics,” said Stephen L. Cox, director, Glass Laminating Solutions and Vinyls -- DuPont Packaging & Industrial Polymers.

DuPont Glass Laminating Solutions provides materials, services and innovations for a better, safer world. The business operates within the DuPont Packaging & Industrial Polymers strategic business unit, part of DuPont’s $5.3 billion Performance Materials growth segment.
