Surlyn® Ionomer
DuPont™ Surlyn® resins are ionically cross-linked thermoplastics based upon ethylene copolymerised with carboxyl groups and a metal ion to give a unique material. They deliver impact toughness, abrasion resistance and chemical resistance in a variety of consumer and industrial products, or use in other plastics as a modifier.
Also typically used as a food contact or seal layer in flexible packaging, DuPont™ Surlyn® packaging resins are optimised for efficient blown film and extrusion coating. Choose from a wide variety of proven grades, to meet specific packaging needs. Overall Surlyn® resins give design versatility, crystal-like transparency and chemical resistance.
