(PlasticsToday) -- The key to solving this challenge lies primarily in even lighter weight automobile construction according to Bayer MaterialScience (Leverkusen, Germany), which is developing innovative and sustainable material solutions based on polycarbonate and polyurethane, which can be in the areas of glazing and the roof structure, for example. In these applications, these materials enable weight reductions of up to 50 percent compared to glass, as already demonstrated by the use of polycarbonate panoramic roofs or fixed side windows in series production.
A roof module with glazing and integrated solar modules developed as a prototype component and concept study by Webasto AG (Stockdorf, Germany) and exhibited in an electric car at the IAA (Frankfurt Auto Show), for example, weighs just 20 kg. The roof module's low weight is thanks largely to the lightweight panoramic panel that employs Makrolon AG2677 transparent polycarbonate, developed by Bayer MaterialScience for automotive glazing.
"Automotive glazing made using our polycarbonate can make a key contribution to offsetting the continuing heavy weight of batteries for electric cars," says Dr. Sven Gestermann, Key Account Manager for Automotive Glazing at Bayer MaterialScience. "A key aim of current developments is to significantly extend the travel range of vehicles. Automotive manufacturers are therefore showing great interest in glazing systems based on our plastic."
