Bynel 50E631 Anhydride modified polypropylene DuPont Polyolefins (PE, PP) >> Polypropylene & 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 5000 resins are anhydride-modified polypropylene. Bynel® 50E631 is based on polypropylene homopolymer. They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polypropylene (PP) resins. Bynel® Series 5000 resins adhere to a variety of materials. They are most often used to adhere to PP, EVOH, and polyamide. These resins are designed for applications in which EVOH or polyamide is melt coextruded with PP or PP copolymers. Bynel® 50E631 can be used in coextrusion processes including blown film, extrusion blow molding, melt and solid phase thermoforming, and cast film or sheet.
