cessing method for an innovative application. The<br />

application itself cannot be blocked by third-party<br />

patents and must belong to a growth market. The<br />

competition must offer sufficient leeway, and not<br />

least: The innovation must promise new commercial<br />

success for the Group.<br />

In all nine projects, the project managers each<br />

pursued several development routes at the same time,<br />

and investigated a number of potential fields of application.<br />

This increased the likelihood of success,<br />

and gave employees enough freedom to find the best<br />

solution for each, and the best possible route to it.<br />

Lightweight construction was a key focus of the<br />

work in the Project House Systems Integration. In the<br />

Automotive Glazing project, PLEXIGLAS® glazing<br />

was developed to make vehicles lighter in weight and,<br />

therefore, increase fuel efficiency and reduce emissions.<br />

The requirements for car windscreens are invariably<br />

high: High mechanical strength must be matched<br />

by high impact strength. The panes have to be UV-<br />

and weather-resistant, guarantee high light transmission,<br />

and withstand temperatures of up to 80 °C without<br />

haziness. Scratch- and abrasion-resistance also<br />

play an important role.<br />

The procedure was different, depending on the<br />

type of glazing and production quantities. For smaller,<br />

injection-molding panes installed in large piece 333<br />

PLeXIGLAS® glazing is<br />

only about half as heavy<br />

as conventional glazing<br />

The speed with which electric vehicles become<br />

operational largely depends on the performance<br />

of the battery. In cooperation with <strong>Evonik</strong> Lita rion<br />

GmbH, the experts in the Project House Systems<br />

Integration have worked on one of the most<br />

important chem ical components of the battery:<br />

The separator, which separates the electrodes in<br />

a battery cell. Based on <strong>Evonik</strong>’s existing<br />

SEPARION® separator, the project house investigated<br />

how the separator could be made thinner<br />

and lighter, for the purpose of increasing the<br />

amount of energy stored in the cell, and making<br />

the battery cells smaller and more compact. The<br />

challenge of this task is in cost-efficient mass<br />

production.<br />
