DAK Americas Sets Up Specialty Polymers Business

Charlotte-based DAK Americas LLC – a producer of polyester staple fibers, polyethylene
terephthalate resins and terephthalic acid monomers, and a wholly owned subsidiary of Mexico-based
Alfa S.A.B. de C.V. – has acquired technology from Wilmington, Del.-based DuPont to manufacture a
select group of 2GT-based polyester resin products previously produced under the DuPont™ Crystar®
name. Crystar specialty resins are used to manufacture monofilaments, nonwovens, packaging and
other engineered polyester products. DAK Americas has established a Specialty Polymers Business
Unit, which will manufacture and market the specialty resins.

“The acquiring of these technologies further enhances DAK’s capabilities and allows DAK to
expand its product offerings into the Special Polymers business,” said Hector Camberos, president
and CEO, DAK Americas.

“These specialty resins fit perfectly with the trade leading products and polyester-based
technologies that DAK has established through its focus on innovation,” said Oscar Montemayer,
senior vice president, corporate development, DAK Americas.
