Explanatory film: How do airplane windows become robust?

Fluctuating cabin pressure, gusting winds, hail – materials used in airplanes and helicopters must withstand extreme strains. Therefore, a special PLEXIGLAS® type must be used.

This means that certified sheets made from cast PLEXIGLAS® are elongated or stretched in a highly complex process. This stretched PLEXIGLAS® sheet is then considerably more robust and therefore ideally suited to the demanding requirements in aviation. Because the material also has high optical quality, is lightweight and can be processed well, the aviation industry has been using it in cabin windows and cockpit panes for years.

Röhm becomes a full-service provider

“For the production of this special material, we need sophisticated technology and a lot of experience, which we have as the inventors of PLEXIGLAS®,” explains Roland Mickal, Head of the Transportation market segment in the Acrylic Products division at Röhm. Röhm is already a leading manufacturer of the necessary primary products for stretched plates and from 2018 onwards will also perform the stretching and polishing process itself. For this purpose, a new plant is being built at the Weiterstadt site, where even significantly larger plate formats than currently possible will be produced. How Röhm produces the primary product for stretched PLEXIGLAS® and how the stretching process then takes place is shown in this film:
