Mitsubishi Chemical Develops New Grade of Bio-based Engineering PlasticDURABIOTM for Automotive Touch Panels

New material features excellent optical properties and high resistance to heat and humidity

DURABIOMitsubishi Chemical Corporation (MCC; Head office: Chiyoda-ku, Tokyo; President: Hiroaki Ishizuka) today announced the development of a new grade of high-performance, high-transparency bio-based engineering plastic called DURABIOTM, using plant-derived isosorbide as its raw material. The new material features excellent optical properties and high resistance to heat and humidity.

MCC will move aggressively to promote sales of DURABIOTM for use in touch panels on automobiles, a sector where demand is expected to increase significantly.

Touch panels for automobiles are used mainly to control air conditioning, audio, and car navigation systems. DURABIOTM offers excellent flexibility in design and can enhance the appearance of automobile interiors, so MCC anticipates much wider use and steady growth in demand.

In contrast to easily breakable glass, transparent plastics such as impact-resistant polycarbonate, are used for the front plate of automobile touch panels for safety purposes. The disadvantage of polycarbonates, however, is distortion in light transmission, which makes it difficult for users to see the touch panel, so a material that could overcome this problem has been eagerly awaited.

MCC’s new grade of DURABIOTM features excellent optical properties, and nearly eliminates distortion in light transmission, making it easy to see the touch panel surface.

Since autumn 2012, MCC has produced DURABIOTM at its Kurosaki Plant (Kitakyushu-shi, Fukuoka; General Manager: Nobuo Fukuda) with an annual production capacity of 5,000 tons.

MCC will develop new applications for DURABIOTM, in addition to touch panels for automobiles, taking full advantage of its high performance, and increase the annual production capacity to 16,000 tons by fiscal year 2015.
