Bynel 40E529 Anhydride modified high density polyethylene DuPont Polyolefins (PE, PP) >> Polyethylene & derivatives SEALANT ADHESIVE Bynel® adhesive resins create a strong, interlayer bond between dissimilar materials in multilayer films, tubes and other packaging and industrial structures. Bynel® can be coextruded or extrusion coated onto a variety of structural, barrier or heat-seal materials. DuPont offers the industry's widest range of standard and custom formulations to meet a variety of high-performance adhesion needs. Bynel® Series 4000 resins are anhydride-modified high-density polyethylene resins. They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins. Bynel® Series 4000 resins are excellent moisture barriers and have a good hydrocarbon resistance. This unique combination of properties makes them useful in a variety of coextrusion applications. HDPE/EVOH tubing and HDPE/polyamide bottles for agricultural chemicals are two examples. Bynel® Series 4000 resins adhere to a variety of materials. They are most often used in coextrusion with EVA, EVOH, polyamide, and PE. BBynel® 40E529 can be used for extrusion coating onto paper or bonding to metal surfaces. It provides strong bonds to nylon and good bonds to EVOH in blown film, cast film, and pipe extrusion processes. Anhydride modified high density polyethylene resin.
