40% Glass Fiber (40 GF) ABS

40 GF ABS is a grade of ABS. It has the highest strength and lowest ductility compared to the other variants of ABS. The graph bars on the material properties cards below compare 40 GF ABS to: styrenic 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.
