40% Glass Fiber (40 GF) PPS
40 GF PPS is a grade of PPS. The graph bars on the material properties cards below compare 40 GF PPS to: polyphenylene 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.
