ASTM D787 Grade 11 Ethyl Cellulose
Grade 11 EC is a grade of Ethyl Cellulose. It has the lowest strength compared to the other variants of Ethyl Cellulose. The graph bars on the material properties cards below compare grade 11 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.
