Announcement of Formal Launch of Toray Tonen Specialty Separator Godo Kaisha

TonenGeneral Sekiyu K. K. (Headquarters: Minato-ku, Tokyo, President: Kazuo Suzuki, herein referred to as "TonenGeneral Sekiyu") and Toray Industries, Inc. (Headquarters: Chuo-ku, Tokyo, President: Sadayuki Sakakibara, herein referred to as "Toray") are pleased to announce that the required regulatory approvals have been obtained and all agreements have been executed for the battery separator film joint venture which we have been jointly progressing. With this, the Toray Tonen Specialty Separator Godo Kaisha joint venture (Chairman: Takeo Togano, President: Reinhart Papen) will begin operation on February 1, 2010.

Toray Tonen Specialty Separator Godo Kaisha will combine ExxonMobil’s and TonenGeneral Sekiyu’s lithium ion battery separator film (BSF) business and technological expertise and Toray’s plastic film processing precision and polymer science technologies to accelerate the development of battery separator film technology to a greater degree than either company could do alone.

In addition, Toray Tonen Specialty Separator Godo Kaisha will build on over 20 years of experience and success in providing separator films for use in the personal electronics market. It aims to create synergies through the introduction of Toray’s next-generation BSF technology while leveraging its film production and development technologies and global operations to contribute to future industry growth of lithium ion battery use in hybrid-electric and electric vehicles.

This announcement follows our press releases on the BSF joint venture made on November 4 and December 21, 2009.
