DuPont Bynel® 3930 Anhydride-Modified Ethylene Vinyl Acetate Adhesive Resin

Bynel® Series 3900 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® 3930 and Bynel® 3933 adhere to a wide variety of materials. They are most often used to adhere to EVA, EVOH, ionomer, polyamide, and PE. Bynel® 3930 and Bynel® 3933 differ primarily in their melt indices. They are both suitable for blown film applications, and Bynel® 3933 can also be used in cast film coextrusion. Both resins can be used to adhere EVOH to PE or ionomer or to adhere polyamide to PE when extra bond strength is required.Physical properties of Bynel® Series 3900 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 other to a particular extrusion process. Information provided by DuPont Packaging Polymers.
