Material Notes:
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.Applications: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® 50E631can be used in coextrusion processes including blown film, extrusion blow molding, melt and solid phase thermoforming, and cast film or sheet.Physical properties of Bynel® Series 5000 resins are typical of polypropylene resins with similar density and melt index values.
