Surlyn 8120 DuPont Packaging & Industrial Polymers EMAA DuPont Surlyn 8120 thermoplastic resin is an advanced ethylene/methacrylic acid
(E/MAA) copolymer, in which the MAA acid groups have been partially neutralized with sodium ions. This very low modulus sodium grade has low hardness and very low stiffness. Increased flexibility is achieved by incorporating a third co?monomer
into the resin during polymerization. It is used alone or in combination with other resins or polymers as a way to tailor flexibility for specific applications. In golf ball covers, for example, it provides a softer feel and imparts greater spin when the ball is in contact with the club face. Surlyn? 8120 normally is processed in a polymer blend by injection molding.

DuPont Surlyn resins (overview)是一種高性能乙烯共聚物,它分為鎂離子聚合物/鋰離子聚合物/鈉離子聚合物/鋅離聚聚合物. 他們的優(yōu)點(diǎn);突出的彈性，硬度和剛度范圍廣泛，優(yōu)良的耐切割，耐磨損.加工方法使用傳統(tǒng)注射成型和壓縮成型的方法和設(shè)備.也可作為增韌劑使用
