DuPont Surlyn® 8320 Ionomer Resin, Sodium

 

Subcategory: Ionomer; Thermoplastic

Key Words: Ethylene/Methacrylic Acid (E/MAA) Copolymer

Material Notes:
Surlyn® 8320 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 ionomer resins or other 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® 8320 is normally processed in a polymer blend by injection molding.
