Dry 30% Carbon Fiber (30 CF) PA 6
Dry 30 CF PA 6 is a grade of PA 6. It has the highest strength and lowest ductility compared to the other variants of PA 6. The graph bars on the material properties cards below compare dry 30 CF PA 6 to: polyamide plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
