Surlyn® 9320W thermoplastic resin is an advanced ethylene/methacrylic acid (E/MAA) copolymer, in which the MAA acid groups have been partially neutralized with zinc ions. This very low modulus zinc grade has low hardness and very low stiffness. Increased flexibility is achieved by incorporating a third co-monomer into the resin during polymerization. The resin can be used alone or in combination with other grades of Surlyn® to provide varying degrees of flexibility, softness and toughness. It can be used as a modifier that yields supertough properties in nylon 6 and 6/6 resins. In golf ball covers, the resin provides a softer feel and imparts greater spin when the ball is in contact with the club face. The resin can be blow molded or extruded into sheets or shapes, but is usually injection molded in blends with other polymers. Data provided by the manufacturer. This product line/trade name was acquired by Dow, but this specific grade was discontinued prior to the acquisition. |
