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