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.

Other Properties:

Lower odor than EVA and solvent-based adhesives
Excellent adhesion
Shorter open times compared to water-based adhesives
Sprayable
Formulation flexibility

Resulting Properties

Amorphous polyolefin based hot melt adhesives have good thermal stability (minimal color changes and reduced gel formation). Melt viscosities can have a wide range due to molecular design and additives. The adhesives have non-tack. They are clear and have excellent room temperature flexibility. APO based hot melt adhesives are used to replace solvent or waterborne adhesives due to environmental, health, or productivity issues. The addition of Aerafin 17 in this formulation decreases viscosity, increases softening point, and shortens open time.
