Dow Bynel® 1123 Modified EVA Adhesive Resin
Categories: Polymer; Thermoplastic; Ethylene Vinyl Acetate; Ethylene Vinyl Acetate Copolymer (EVA), Adhesive/Sealant Grade

Material Notes: Bynel® Series 1100 resins are modified ethylene vinyl acetate polymers. They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins.

Applications: Bynel® 1123 and 1124 are acid modified ethylene vinyl acetate polymers that differ only in their rheology. They adhere to a wide variety of materials. They are most often used to adhere to PE, ionomer, PET, EVA, PVC, PVDC, PS, HIPS, PC, and PP. Bynel® 1123 and 1124 can be used in coextrusion processes including: blown film cast film/sheet extrusion coating extrusion lamination Bynel® 11E554 and 11E573 are modified ethylene vinyl acetate polymers designed to be used as extrudable adhesive resins or sealing layers for lidding applications. It is most often used to adhere to PE, PP, PET, PS, and PS foam.

Physical properties of Bynel® Series 1100 resins are typical of EVA resins with similar density and melt index values. The rheology characteristics of each grade are different, so one may be better suited than the others to a particular extrusion process.
