Innovative solutions for automotive glazing

Automotive glazing

Large, transparent surfaces like panoramic roofs, transparent body panels or side/rear windows are becoming increasingly popular in the automotive industry. Makrolon® polycarbonate, Bayblend® (PC+ABS; PC+ASA blend) and Makroblend® (PC+PBT; PC+PET blend) are the materials of the future for automotive glazing.

Use of Makrolon® and polycarbonate blends in automotive glazing

The benefits of Makrolon® really come into their own in this application in particular. A polycarbonate panoramic roof cuts weight by up to 50 percent compared to glass roofs, resulting in a marked decrease in CO2 emissions. The high impact resistance of polycarbonate also offers a vital safety benefit. There is great potential for functional integration, and the design freedom allows new forming possibilities.

Utilizing a high-gloss polycarbonate bezel allows manufacturers to maximize the glass-like surface area of a panoramic roof. The strength and transparency of Makrolon® makes this unique design possible.

Life cycle analysis

A life cycle analysis reveals the resource efficiency of polycarbonate glazing. One kg of polycarbonate glazing saves between 14 and 22 kg of CO2 emissions over its total life cycle compared to conventional glass.

In automotive glazing, Covestro focuses on the development of innovative products and cutting-edge technology in injection molding and coating processes.

At its injection molding pilot plant in Leverkusen (Germany), Covestro has devised a glazing technology cell that simulates production conditions. Injection-compression moldingtwo-component injection molding and film insert technologies were studied intensively to fulfill the demanding requirements of automotive glazing.

In addition to Makrolon® grades tailor-made for automotive glazing, Covestro provides advice on coating choices and application.
