30% Vinyl Acetate EVA
30% VA EVA is a grade of EVA. The graph bars on the material properties cards below compare 30% VA EVA to: ethylene copolymers (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.
