Eastman Chemical Co.'s Tsunami-brand copolyester product line has been renamed Cadence.
The company deemed the Tsunami name inappropriate following the magnitude-9.0 earthquake off Indonesia's Sumatra on Dec. 26 and the resulting disaster.
The recyclable copolyester is used in decorative lamination in calendering four of the nine layers in China's new, second-generation personal identification card. Each layer is 65-330 microns thick with a semiconductor chip encapsulated in the largest layer. The cards are made in China.
The China Ministry of Public Security began issuing the cards in March 2004 and expects to circulate more than 1 billion cards by the 2008 Olympic games in Beijing. The cards are intended to reduce both counterfeit paper identification and bureaucratic issues in administering social services.
Kingsport, Tenn.-based Eastman makes Cadence in Kingsport and Southeast Asia.
