NEMA Grade CE (FBG) Canvas-Phenolic Laminate
NEMA grade CE is a grade of NEMA laminate. The graph bars on the material properties cards below compare NEMA grade CE to other thermoset plastics (top) 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.
