PA11 – Polyamide 11 PA11 CF40

AKROMID® NEXT U3 ICF 40 1 black (8238)

AKROMID® NEXT U3 ICF 40 1 black (8238) is a 40% carbon fiber reinforced Polyamide 11 which consists of > 97% renewable raw materials based on castor oil. Its low density as well as excellent ductility even at lower temperatures combined with high stiffness and strength enable the use for demanding applications, e.g., for lightweight construction or sports & leisure.

The production of large-volume parts is possible with high throughputs > 1 kg/h in 3D-printing with pellets in screw extrusion additive manufacturing and Fused Granulate Fabrication (FGF).
