After a four-year break, the aviation and aerospace industry is gathering at the 54th Paris Air Show held from June 19 to 25. Röhm GmbH is presenting large stretched PLEXIGLAS® sheets and other aviation materials at Booth A94 in Hall 3 at the Le Bourget Parc des Expositions (Paris, France). “Glazing for aircraft was one of the first applications for cast acrylic glass sheets once PLEXIGLAS® was registered as a brand 90 years ago,” says Florian Laub, Head of the Transportation market segment at Röhm. “Since then, we have developed a high-performance portfolio of special products for the aviation industry; all of which meet the stringent requirements of the respective applications.”

Cast and stretched polymethyl methacrylate (PMMA) in the PLEXIGLAS® brand has been used for cabin windows and cockpit windshields in airplanes and helicopters for many decades now thanks to its excellent optical quality, low weight and tight thickness tolerances. On top of this, Röhm is also presenting an innovation at the Paris Air Show: A special feature for aviation materials that does not require coloring, yet still absorbs ultraviolet and infrared light. This provides aircraft passengers with a higher level of protection and reduces heat accumulation in the cabin, which in turn conserves the energy required for air conditioning.

Large formats

Materials for aircraft construction must satisfy the highest quality demands and be extremely robust. Compared to cast PMMA sheets, stretched PMMA sheets have improved impact resistance and increased chemical resistance. Stretched PLEXIGLAS® from Röhm is certified to European AECMA 4366 standard and US MIL-P-25690 standard and are available in thicknesses up to 28 mm and sizes up to 4000 mm × 3000 mm. “Large formats satisfy the trend toward larger aircraft windows, while allowing for efficient production processes at the same time, as a greater number of windows can be produced from a single sheet,” Laub adds. Thus, these XXL formats contribute to resource-saving aircraft construction. A further advantage is that scratches in the material can be easily sanded and polished, which in turn extends the service life of the sheets in the respective use case.

Permanent and maximum transparency

Visitors to the Röhm booth can view another special feature of the 1.80-meter by 1.80-meter sheet of the brand acrylic glass for themselves: With a transmittance level of 92 percent and an undistorted view, the material meets the high optical standards in aircraft construction that do not permit any irritations in the material. And in the long term, too: PLEXIGLAS® is extremely resistant to weather and aging – while protecting pilots against UV radiation at the same time. These properties make PLEXIGLAS® a much sought-after material for cockpit windshields and aircraft canopies.
