DuPont™ Surlyn® resins (overview)

DuPont™ Surlyn® ionomer resins are a family of high-performance ethylene copolymers containing acid groups partially neutralized using metal salts such as zinc, sodium and others. The result is an ionically strengthened thermoplastic with enhanced physical properties versus conventional plastics. The DuPont manufacturing process for Surlyn® enables highly tailored combinations of properties: outstanding resilience, broad hardness and stiffness range, and excellent resistance to cuts and abrasion - all highly desirable for golf ball applications.

Surlyn® ionomers can be melt-processed using conventional injection molding and compression molding methods and equipment, to create parts of various designs and gauges. Because of their performance properties and processing versatility, Surlyn® resins have been widely adopted, in neat or blended form, as premium materials for golf ball covers, mantles, intermediate layers, and other components.

Commercially available DuPont™ Surlyn® resins for golf balls include the following (with links to properties data and safety data sheets).
