German motor company Daimler AG and one of leading polymer companies Bayer MaterialScience AG are to cooperate more intensively in the future on the development of polycarbonate (PC) automotive glazing. As part of the expertise offered by Bayer MaterialScience under its "BayVision" brand, Daimler will investigate other potential applications for PC glazing and assess the suitability of this technology for future series production vehicles. For Daimler, the main advantages of PC glazing are weight savings and the associated reduction in CO2 emissions including design freedom and simpler functional integration. The roof module of the Mercedes GL and the panoramic roof of the smart fortwo are currently in series production, and both use Makrolon® AG2677 and Makroblend® 7665 or Bayblend® T 95 MF from Bayer MaterialScience.
"BayVision will set new standards for tomorrow's motor vehicles and, in addition to reducing CO2 emissions, will open up completely new horizons in vehicle design", says Dr. Günter Hilken, head of the Polycarbonates Business Unit at Bayer MaterialScience. "This intensified future cooperation with Daimler in the field of polycarbonate glazing represents another milestone in the development of products and technologies for automotive construction." BayVision combines the core competence of Bayer MaterialScience, extensive expertise in glazing raw materials - i.e. Makrolon® polycarbonate and its blends - and a comprehensive applications service with in-depth developments in technology. Tools such as rheological and mechanical CAE simulation programs are available as standard. The experts at Bayer MaterialScience also study, among other things, the thermal expansion behavior of glazing modules and offer customers advice on design issues.
