DuPont™ Sorona® for Fibers• Textiles - Commercial• Carpets - Commercial• Automotive Interior – In development

DuPont™ Sorona® polymer • EP Resins - Commercial this year• Packaging - Commercial this year

• Sorona® carpets offer superior built-in stain resistance, resilience, and softness

•Sorona® will not retain odors like current carpet materials

•Sorona® moisture regain is very low and therefore resistant to mold and mildew growth

•Lower environmental footprint
