30% Glass Fiber (30 GF) LCP
30 GF LCP is a grade of LCP. The graph bars on the material properties cards below compare 30 GF LCP to: polyester 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.
