DuPont Bynel® 3861 Anhydride-Modified Ethylene Vinyl Acetate Adhesive Resin

Subcategory: Ethylene Vinyl Acetate; Thermoplastic

Key Words: EVA; DuPont Packaging Polymers

Material Notes:
Bynel® Series 3800 resins are anhydride-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® 3810 and Bynel® 3859 adhere to a wide variety of materials. They are most often used to adhere to PE, PS, and EVOH. They can also be used to adhere to polyamide. They provide outstanding adhesion to PS. They are typically used to bond PS to EVOH barrier resins in opaque thermoformed container applications. They are also well suited to structures such as PS/Bynel® /EVOH/Bynel® /PE, because they adhere to polyolefins in addition to PS and EVOH. The primary difference between Bynel® 3810 and Bynel® 3859 is their rheology. Bynel® 3810 and Bynel® 3859 can be used in coextrusion processes including: cast film/sheet blown film Bynel® 3860 and Bynel® 3861 are most often used to adhere to PE, ionomer, PS, EVOH, and PET. They can also be used to bond to PP, PVC, PVDC, PC, and polyamide. Bynel® 3860 and Bynel® 3861 are used in transparent PS/EVOH/PE structures as well as PET/PE cast sheet. Bynel® 3860 is used to coextrusion coat EVOH onto OPP. The primary difference between Bynel® 3860 and Bynel® 3861 is their rheology. Bynel® 3860 and Bynel® 3861 can be used in coextrusion processes including: cast film/sheet blown film extrusion coating Bynel® E418 provides good adhesion to unprimed oriented polyester film. It will also adhere to PE, EVA, Surlyn® , EVOH, PET, PC, PS, polyamide, PVC, and PVDC. Bynel® E418 will also bond to fabric and nonwovens.

Physical properties of Bynel® 3800 Series 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.
