DuPont China Holding Co. Divests Interest in Copolymer Acetal Joint Venture
Focuses Development Efforts toward Delrin® Acetal Homopolymer High-Performance Applications

Shenzhen, China, June 10, 2013

DuPont China Holding Co. Ltd. announced today that it has agreed to a share transfer agreement of its interest in the Asahi-DuPont POM (Zhangjiagang) Co. Ltd. (ADZ) joint venture with Asahi Kasei Chemicals, which began manufacturing acetal (POM) copolymer resins in 2004.

DuPont and Asahi Kasei Chemicals will work to receive approvals from the Chinese government and initiate communication with customers on transition plans.

This decision is consistent with DuPont’s strategy to focus market and development efforts on the high-performance, high-precision POM applications where acetal homopolymer is typically required.

DuPont, which invented acetal 60 years ago, supplies the China market with DuPont™ Delrin® acetal homopolymer from its facility in Shenzhen as well as from the other Delrin® manufacturing sites around the world. DuPont will continue to strengthen its supply chain capabilities to further increase the volumes of Delrin® sourced locally within China.

Delrin® acetal homopolymer is typically used in high demanding applications in the automotive, industrial and consumer markets, including safety systems or electrical motors, where high reliability during the application’s life cycle is required.

DuPont Performance Polymers has been active in China for nearly 3 decades and has recently expanded its DuPont Shanghai research and development center to strengthen collaboration and application development capabilities.
