Bio-Based Plastic Alloy with High Impact Strength

Aiming for a sustainable society, we have succeeded in creating a novel bioalloy based on polyamide 11―a 100% bioplastic derived from inedible plants―and polypropylene (PP), using a green process.
With this process, it is possible to control the bioalloy morphology to create novel structures, such as the “salamis in co-continuous phase structure” shown below, and to achieve both excellent impact strength and high flexural modulus, which has never been accomplished.
The 10-fold greater impact strength of the bioalloy compared to that of PP―which is conventionally used in automotive interior parts―makes it suitable for various parts that require high impact resistance. This joint research has been carried out with TOYOTA BOSHOKU CORPORATION.
