Material

PA 2241 FR

PA 2241 FR is a polyamide powder that contains a chemical flame retardant. This high-performance material is ideal for manufacturing flame-resistant parts with high mechanical properties. It is FAR 25.853 compliant, making it suitable for aeronautics and aerospace applications, and is also available in an Airbus certified grade, in accordance with AIPI 03-07-022. 

A series of 3D-printed repair kits with EASA 21.J quality labels. The kit contains small white plastic parts made of flame-retardant polyamide, designed by Expleo. These parts are used to replace commonly broken latches on Boeing 737 dado panels.
