Fujitsu Limited and Fujitsu Laboratories Limited have developed a new polymer with a high bio-content that uses castor oil extracted from the seeds of the castor bean, featuring superior flexibility that can withstand repeated bending without causing the whitening that often occurs when such materials are strained. After adding high-density fillers to increase strength, the polymer maintains good impact-resistance and thus it is estimated to find application in PC chasses, small components of notebook PCs and mobile phones, such as connector covers.
In 2002 Fujitsu started using bio-based polymers based on polylactic acid, made from materials including corn, in the chassis of the FMV-BIBLO notebook PC. Later, Fujitsu and Fujitsu Laboratories worked with a major French chemical company, Arkema, and succeeded in developing a new bio-based polymer plastic that has as its principal component polyamide-11 (PA-11) which is derived from castor oil.
