Dow Surlyn® 8940 Ionomer Resin, Sodium
Categories: Polymer; Thermoplastic; Ionomer; Ionomer, Molded

Material Notes: Surlyn® 8940 thermoplastic resin is an advanced ethylene/methacrylic acid (E/MAA) copolymer, in which the MAA acid groups have been partially neutralized with sodium ions. The amount of MAA and neutralization levels for this grade are optimized to deliver excellent clarity and high stiffness compared with other grades of Surlyn®. The resin can be injection molded, and is processable by extrusion into sheets or shapes. It complies with the provisions of U.S. Food and Drug Administration (FDA) Title 21 Code of Regulations 177:1330 - ionomer resins.
