Novel Amorphous Polyalphaolefins (APAO) in Hot Melt Adhesive Formulations, 1991 Hot Melt Symposium Proceedings
On-purpose amorphous polyalphaolefins (APAO), made by direct reactor synthesis, are being used in increasing amounts in hot melt adhesives (HMA). The products are tailored copolymers of ethylene, propylene or 1-butene and exhibit a range of melt viscosities, needle penetrations and softening points, surface tackiness and open times; all closely reproducible.
This paper describes briefly the development of these novel on-purpose APAOs. It will show data on physical and mechanical properties as well as present characterization data which intends to show the versatility of these compounds in some general HMA formulations.
