The new lightness of driving
Greater efficiency and safety with wrap-around glazing made of polycarbonate
Glass and metal: This combination has been the absolute standard in automotive manufacturing for roof components since day one. Can’t we do better? We most certainly can! Especially when a new material displays the same strengths as a conventional one, but overcomes its weaknesses. Covestro researchers have no doubt that transparent polycarbonate can do both.
This high-tech plastic has two decisive advantages over glass: First, it weighs only half as much while offering comparable strength. That makes a car more fuel efficient and therefore more eco-friendly. Second, polycarbonate can be shaped much more easily than glass and therefore is ideal for designing complex geometries. It opens up a whole new world of possibility for automotive designers. And as we know, a signature design is one of the most important criteria for standing out among the crowd of new vehicles.
Instead of the usual heterogeneous structure of windows, pillars and roof, the entire roof module can now be a monolithic, transparent dome, thanks to polycarbonate. Not only does this look spectacular, it also gives passengers a complete 360° panoramic view. Luxury thanks to new perspectives, and a big plus for the safety of other traffic participants.
A new directive only recently approved the use of polycarbonate for front windshields. This was a crucial step for the automotive industry, because it paves the way to innovative wrap-around glazing that takes design, efficiency and safety to a whole new level for future vehicle models. Covestro will continue to support automotive manufacturers and suppliers along the way.
