Surlyn 8140 DuPont Packaging & Industrial Polymers EMAA DuPont Surlyn 8140 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 higher hardness and stiffness compared with other sodium ionomer grades of Surlyn?. The resin is ideal where high stiffness, high clarity and good abrasion resistance are desired. In golf ball covers, the resin provides good cut resistance, impact durability, high resilience and increased coefficient of restitution,particularly when used in blends with other cations. The resin is normally injection molded
