| Surlyn 8320 |
 |
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 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 8320 normally is processed in a polymer blend by injection molding. |
