| Surlyn 8120 |
 |
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. |
