Fujitsu Ltd. has developed a high-biodegradable-content poly¼mer that it eventually might use for electronic components such as connector covers.
The Tokyo conglomerate said its new polymer features better flexibility than other biopolymers. It is based on castor oil transformed into nylon 11. Fujitsu reorganized the configuration of the polymer chain to yield a more flexible plastic that doesn't whiten when repeatedly bent.
The company conducted the research in conjunction with Paris-based chemical company Arkema Group, the world's only producer of nylon 11 by conventional chemistry.
Fujitsu reported the castor oil raw material boosts the biodegradable content of the new nylon to 60-80 percent. After high-density fillers are added to increase strength, the firm said, the polymer maintains good impact resistance, making it suitable for electronic housings and other components. The company hopes to begin using the new polymer in such applications in 2008. The research complements Fujitsu's work on polylactic acid biopolymers.
Fujitsu America Inc. of Sunnyvale, Calif., is the main U.S. subsidiary of the Tokyo firm.
