Flame retardant filaments for aerospace & railway

Materials used in the aerospace industry are subject to particularly stringent requirements and regulations. In addition to key characteristics such as maximum reliability, special protection against fire hazards, smoke generation and temperature resistance, the materials and components used must also meet the demands for more sustainable use of resources.
The use of high-performance plastics, with all their beneficial properties and wide range of application possibilities, offers many options in this respect. 
With our flame retardant filaments specially developed for the aerospace sector, we offer 3D printing materials that meet the high requirements of the aerospace industry and are tested and certified according to FAR 25.853 and UL94 V-0.
Even complex geometries can be manufactured in a cost-efficient and resource-saving manner.

Our flame retardant filament portfolio

Depending on the application, various high-performance plastic filaments from Ensinger are suitable for use in the aerospace sector. In addition to inherently flame retardant materials such as PEEK or PEI, we also offer TECAFIL PC FR natural, a cost-effective filament that was developed specifically for use in aircraft interiors.
