30% Carbon Fiber (30 CF) PSU
30 CF PSU is a grade of PSU. The graph bars on the material properties cards below compare 30 CF 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.
