 |
Surlyn 9721 thermoplastic resin is an advanced ethylene/methacrylic acid (E/MAA) copolymer, in which the MAA acid groups have been partially neutralized with zinc ions.
The amount of MAA and neutralization levels for this grade are optimized to deliver low-temperature toughness, plus abrasion resistance and stiffness.
It is ideal for modifying nylon resins for increased Izod impact performance.
The resin can be injection or blow 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. |
