Mitsubishi Chemical launches plant-based engineering plastic

| By Mary Bailey

The Mitsubishi Chemical Group (MCG Group; Toyko) will begin providing samples of DURABI D93 Series (under development), a new grade of the plant-derived bioengineering plastic DURABI with a higher biobased synthetic polymer content.
DURABIO is a bioengineering plastic made using the renewable plant-derived raw material “isosorbide” that reduces the consumption of petroleum, an exhaustible resource, and contributes to lowering greenhouse gases because the plants used as raw materials absorb carbon dioxide during the growth process.
The D93 series (under development) developed by the MCG Group has a biobased synthetic polymer content of approximately 74%, an improvement of more than 15% from the 58% of the D73 series, the previous leader, while retaining such features of DURABIO™ as transparency, scratch resistance, and coloration and boasting higher heat resistance (deflection temperature under load: 131°C) than earlier products. It also has a surface hardness comparable to that of acrylic resin and can be used across a wide range of sectors, including information electronic equipment, automotive parts, and daily necessities.
