DuPont Debuts Nomex® KD Filter Material In China

January 15, 2010 — DuPont Protection Technologies launched a new DuPont™ Nomex® KD nonwoven filter
material at a recent Bag Filter Exhibition in Shanghai, China. Especially beneficial for hot gas
industries, the new filter material is based on innovative technology that blends DuPont™ Nomex®
and Kevlar® fibers.

This new technology improves filtration performance, dust retention and efficiency by
increasing the surface area of filter media. Hot gas industries such as asphalt and cement
manufacturers need efficient and effective filtration solutions for high temperature applications.
The Bag Filter Exhibition provided an opportunity for DuPont to reach potential customers, promote
the new offering and increase the company’s exposure in Asian markets.

The exhibition booth featured green accents, supporting the message to manufacturers that
Nomex® KD can help them meet stringent national and local air standards. The DuPont team at the
exhibition reported that many visitors showed significant interest in the new product.  In
addition to its improved filtration performance, Nomex® KD has the potential to reduce costs and
increase reliability.

During the exhibition, Qiqi Wang, applications researcher for Performance Materials – Asia
Pacific, and Jason Zhu, sales representative for Performance Materials – China, presented a paper
on the technology and merits of Nomex® KD for the filter bag industry at the Technical Conference.
Many conference participants expressed interest in the product and appreciation to DuPont for
introducing Nomex® KD to industries in China.

DuPont™ Nomex® has been widely regarded as a material of choice for its reliability and
excellent filtration performance in elevated temperature applications in hot gas industries for
more than 40 years.
