Toyota Develops PP- & Plant-derived PA11-based Plastic Alloy with High Impact Strength
Toyota Boshoku Corporation, among the premier manufacturers of automotive interior systems, and Toyota Central R&D Labs., Inc., contributing to present and future businesses of Toyota Group companies through technological innovations, announce that they have developed an original technique to realize a bio-based plastic alloy with top-class impact strength. The bio-based plastic alloy (bio-alloy) is made from polyamide 11 ( PA11 ), a 100% bio-based resin originating from plants and synthesized by castor oil *1 extracted from Ricinus Communis (castor bean plant) as a raw material, and polypropylene ( PP ) derived from petroleum-based resin. The performance of this high impact bio-alloy surpasses polycarbonate alloys. The impact strength of the bio-alloy was achieved by controlling the phase structure of PP and PA11 at the nano level through a "salami structure *2 " mixture (dispersion) resulting in the world's fi...
