During the Second World war, polymethyl methacrylate (PMMA) was widely used in military aviation as an alternative to glass for airplane windows.

PMMA has many advantages over glass: allows for the design of complex shapes, requires few metal supports that can block the field of vision, prevents optical distorsions, makes the final product substantially lighter.

Altuglas® PMMA sheet can be found on all types of airplanes (gliders, recreational/commercial/military aircraft):

  • cockpits
  • portholes
  • windshields
  • exterior lighting
  • helipcopter windscreens
Special aerospace Altuglas® sheet can be use for military and commercial planes.

The long list of advantages of Altuglas® PMMA makes it the preferred product for aerospace windows:

 

  • Good long-term mechanical peformance
  • Resistance to chemicals, heat, cracking, shock, weather and temperature fluctuations
  • Superior surface quality (minimum impurities)
  • Hardly any optical distortion or deviation

 

In sectors where safety is a top concern, both the mechanical and optical quality of Altuglas® PMMA and the reproducibility of its characteristics have to be flawless.
