Mazda CX-5 grill made from Mitsubishi’s engineering bioplastic

In collaboration with Mazda Motor Corporation, based in Hiroshima, Japan, Tokyo-based Mitsubishi Chemical Corporation has developed a new grade of Durabio bio-based engineering plastic that can be applied to large automotive exterior components. The new grade is now being used for the front grill of the Mazda CX-5.

nMCC’s Durabio is a bio-based engineering plastic made from isosorbide deriving from renewable plants. The material features superior properties compared to general bio-based engineering plastics in terms of impact resistance, heat resistance and weathering, among other aspects. It also has good color capability and, simply by adding pigments, creates a “mirror-like smooth surface and deep color tone” surpassing painted products with similar properties. Furthermore, its hard surface and resistance to scratch eliminates the need for any coating process, enabling reduction in volatile organic compound (VOC) emissions during manufacture. Capitalizing on these features, Durabio has been adopted for pillars and other exterior design components, in addition to interior components, thus enhancing a broad range of applications in the automotive sector.
The new grade of Durabio is claimed to offer superior resistance to impact and weathering and better formability due to improvement in resin composition compared to conventional grades, thereby making it possible to apply the new product to the front grill and other large exterior components. It is expected to be adopted for future models launched by Mazda following the CX-5.
MCC will continue to accelerate R&D on its Durabio material to expand applications not just for automotive interior components but also for larger exterior design components - contributing to the production of environmentally friendly motor vehicles.
