ASTM D787 Grade 6 Ethyl Cellulose

Grade 6 EC is a grade of Ethyl Cellulose. The graph bars on the material properties cards below compare grade 6 EC to: cellulosic 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.
