News Release from Dupont Dow Elastomers

10/13/2003

High performance speciality products needed Metallocene gas phase EPDM technology and Viton® Extreme™ high performance specialty products based on Advanced Polymer Architecture (APA) will be among the new technology and products featured by DuPont Dow Elastomers at its booth (#940) the American Chemical Society Rubber Division Expo and technical meeting in Cleveland, Ohio, Oct. 14 to 16.

Combining metallocene technology with gas phase EPDM production has allowed DuPont Dow to break new ground in EPDM. DuPont Dow has brought to market five new Nordel® MG hydrocarbon rubber grades and in 2004 will introduce an ultra high diene grade aimed at sponge weatherstripping. Initial offerings include three very high Mooney viscosity (over 100) grades. According to DuPont Dow, users upgrading existing formulations with high molecular weight Nordel® MG experienced significant improvement in mixing time, compound extension and fill factor yielding improved total economics. The new base-resistant Viton® Extreme™ fluoroelastomers are designed to meet the demanding performance requirements that are not currently met by traditional high performance elastomers. These new specialty elastomers combine the excellent thermal resistance of Viton® with the unique resistance to chemicals and to environments that have historically exceeded the performance of conventional fluoroelastomers.

DuPont Dow's proprietary Advanced Polymer Architecture technology has provided a significant upgrade to many specialty Viton® fluoroelastomers with improvements in both processing and end-use properties. For rubber processors, the new Viton® peroxide cure types offer exceptional flow properties, fast curing and excellent demolding. They will be able to achieve the improved compression set resistance and sealability demanded by end-users with low-to-no postcure.

In addition to Nordel® IP and Nordel® MG hydrocarbon rubber and Viton® products, DuPont Dow will feature Hypalon® chlorosulfonated polyethylene at the exposition. Hypalon® has shown a long life in harsh environments and is used in a wide range of industrial and automotive applications that require high performance. For more than 50 years, it has offered advantages such as strength and flexibility, weatherability, chemical, biological and flame resistance and design flexibility.

As part of the technical program, a number of DuPont Dow presenters will offer technical papers. The six technical papers will include:
