Bynel® Series (Coextrudable adhesive resins)

Versatile Adhesive Resin Joins Dissimilar Materials Join the “unjoinable” to optimize structural integrity and avoid delamination in films, bottles, tubes, and other applications.
DuPont™ Bynel® coextrudable adhesive resin gives manufacturers and converters powerful solutions for multi-layer adhesion needs. It is used as a tie layer, creating a strong bond between dissimilar materials in bottles, tubes, thermoformable sheets, films, and non-packaging uses such as piping and building panels.
Bynel® adhesive resin can be a cost- and process-efficient choice, available pre-compounded in a range of grades. It can help optimize barrier, heat-seal and other functionalities in coextruded blown & cast film, extrusion coating/lamination, cast sheet, coex tubing, and blow molding. Strong, flexible, interlayer adhesion supports replacing heavy glass or metal containers with lightweight, multi-layer barrier packaging, which can help reduce fossil fuel use (and costs) in distribution.

Grades



Bynel® 4109
BYNEL® Series 4100 series resins are anhydride-modified, linear low-density polyethylene (LLDPE) resins. All BYNEL Series 4100 series resins are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene resins.

Bynel® 41E710
Bynel 41E710 is a grade with a higher level of anhydride modification, and is mainly intended for use as a component in a blend with other polyolefin resins. It is not intended for extrusion in its pure form in typical extrusions or coextrusions.

Bynel® 41E556
BYNEL® Series 4100 series resins are anhydride-modified, linear low-density polyethylene (LLDPE) resins. All BYNEL Series 4100 series resins are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene resins.

Bynel® 22E757
BYNEL® Series 2200 resins are modified ethylene acrylate resins. They contain a temperature stable ester which makes them functional in high temperature coextrusions. They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins.
