Denso using plant-derived plastics for Toyota Motor's productsKARIYA, JAPAN: Japanese automotive components manufacturer Denso Corporation is using bio-polycarbonate (PC) made from starch and urethane resin extracted from castor oil in some of its products, informed the company in a media release.
Currently, Denso's starch-derived bio-PC, which provides high hardness, yet can be shaped into complex designs, is being used to make plastic bezels for Toyota Motor Corporation’s genuine car navigation systems.
The company said, "Starch-derived bio-PCs have higher surface hardness, better optical characteristics, and superior hydrolytic stability than conventional petroleum-derived PCs. Moreover, they refract less light, exhibit better color-forming properties, and thus do not need to be painted before being used."
Castor oil, a vegetable oil extracted from castor beans, is used as a material in paints, waxes, and other products.
Automotive exhaust gas sensors, which measure the concentration of specific gases present in vehicle exhaust gases, must have high heat resistance. Therefore, the resins used in sensor control units have traditionally been expensive silicone-type resins. Denso’s newly developed urethane resin costs less than silicone resins and can withstand up to 150 °C, while significantly reducing the amount of gases produced when being melted and formed into shapes. This is the first such resin of its kind in the world, claims Denso.
