40% Glass Fiber (40 GF) PSU
40 GF PSU is a grade of PSU. It has the highest strength and lowest ductility compared to the other variants of PSU. The graph bars on the material properties cards below compare 40 GF PSU to: sulfone 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.
