Biochemical plastic “DURABIO®” from Mitsubishi Chemical Corporation (Headquarters: Chiyoda-ku, Tokyo; President: Masayuki Waga; hereinafter “Company”) Zhi, “Lenovo”) was adopted for the smartphone housing (3D shape back plate).
Lenovo actively sells smartphones that incorporate advanced technologies and designs. This time, DURABIO is not only an environmentally friendly material, but also appreciates the physical properties required of the chassis. I decided to adopt it.
Conventionally, metallic materials have been used for smartphone housings, but there is concern over blocking radio waves for future 5G communications, and there is a need for transfer to non-metallic materials. However, glass is vulnerable to impacts and easily breaks, while conventional resins have their own physical properties such as transparency, scratch resistance, impact resistance, and optical distortion.
DURABIO® is a bio engineering plastic that uses isosorbide, a renewable plant-derived material, and is a plastic with excellent balance of physical properties such as transparency, scratch resistance, impact resistance, and optical properties. It can also be applied to designs that require more freedom in smartphone housings.
In order to realize the “KAITEKI *” set forth by the Mitsubishi Chemical Holdings Group, we will continue to accelerate research and development and application expansion of plant-derived plastics, including DURABIO®, through the supply of environmentally friendly and high-value-added products. We will contribute to building a recycling-oriented society and achieving the SDGs.
* This is the original concept of the Mitsubishi Chemical Holdings Group, which means that people, society, and the comfort of the earth will continue.
