Ethylene Methyl Acrylate (EMA)

EMA is a thermoplastic, further classified as an ethylene copolymer. It has a fairly high ductility among thermoplastics. In addition, it has a very low tensile strength and a fairly low density. The graph bars on the material properties cards below compare EMA 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.
