Material Notes:

Surlyn® 7930 thermoplastic resin is an advanced ethylene/methacrylic acid (E/MAA) copolymer, in which the MAA acid groups have been partially neutralized with lithium ions. The amount of MAA and neutralization levels for this grade are optimized to deliver low temperature toughness, excellent clarity, and extra stiffness compared with other grades of Surlyn®. The resin can be injection or blow molded, and is processable by extrusion into sheets or shapes. Typical performance properties are shown below:Data provided by the manufacturer.
