Fujitsu modifies bio-polymer for better impact resistance

1 June 2006

Japanese company Fujitsu has developed a new bio-based polymer that retains the heat resistance and mouldability of its previously developed bio-based polymer, while improving impact resistance by 50 percent. Fujitsu says that it has succeeded in developing a prototype mobile phone case using the new bio-based polymer.

In collaboration with Toray Industries, Inc., Fujitsu has developed the new bio-based polymer with high impact resistance, by further refining the microstructure and improving the compatibility of polylactic acid with polymer alloyed-polycarbonate, which has a high glass transition temperature. The new bio-based polymer has the same heat resistance and moulding properties of the bio-based polymer previously developed by the companies. The 50 percent improvement in impact resistance means that the plastic can now be applied to various mobile devices.
