They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins. Restrictions Material Status .. Commercial: Active Typical Characteristics Characteristics / Benefits Physical properties of BYNEL Series 1100 resins are typical of EVA resins with similar density and melt index values. Applications BYNEL 1100 series resins adhere to a wide variety of materials. They are most often used to adhere to PE, ionomers, EVA, and in some cases PVC, PS. HIPS, and PP.

The adhesive is designed to bond materials that would not ordinarily adhere to each other. In most cases, peel strength is used as a measure of performance. Although this is a convenient test, peel strength is affected not only by adhesion, but also by peel angle, separation rate, temperature, and tensile and modulus properties of the materials, and often by the time elapsed since the formation of the bond. Post-treatment of the multi-layer structure, such as heat sealing, thermoforming or orientation can also affect peel strength. If peel strength is used as a measure of adhesive performance, it is imperative that peel strength be evaluated not only at the time of manufacture, but throughout the life of the product and under all the various conditions to which the structure will be exposed. Only then can the performance of the adhesive be related to peel strength. Processing Information
