Applicable Base Polymer Properties
Adhesives that are based on polyolefin resins are used mainly as hot melt adhesives in either block or film form. In film form, they provide excellent peel strength as a hot laminating adhesive for plastic films and metallic foils. Polyolefin adhesive films are also used in extrusion coating. In this application a ply of adhesive is extruded onto a structure to provide a heat-sealing medium for later bonding.
Aerafin resins are saturated, low molecular weight, propylene-based olefin polymers with good low temperature properties for adhesion in low temperature conditions and compatibility with a wide range of waxes and hydrocarbon tackifying resins.
