Adopted as resin panorama roof of Prius α

May, 18, 2011

Mitsubishi Engineering-Plastics Corporation (HQ: Minato Ward, Tokyo. President: Yasuhiko Kijima) has succeeded in developing a polycarbonate (PC) resin material with good heat stability by using original compounding technique, and chosen to be adopted as a resin panorama roof of "Prius α". This panorama roof that Toyota Industries Corporation developed and produced, has world's biggest size as a resin panorama roof, and achieved a significant weight saving against inorganic glass.

Polycarbonate (PC) resin has been attracting attention as an inorganic glass alternate material for automobile from the weight saving point of view, since it has high transparence and impact resistance. On the other hand, degradation in physicality by retention inside the molding machine was always been a problem when applying to large-size molded product like this product. To be used as a resin panorama roof, transparent PC material with retention heat stability and hard coat adhesion which could not have been achieved by conventional technology, and reinforced PC alloy material for window frame with improved retention heat stability have been developed with cooperation of Toyota Industries Corporation, and achieved the product specification, then finally got adopted.
