Hot Melt Adhesives (HMA) are generally produced by compounding several components; polymers, tackifiers, and waxes or oils.

Due to their high compounding, storage, and application temperatures, hot melt adhesive formulations are extremely susceptible to thermal oxidation and degradation. Degradation of the overall formulation or an individual component will negatively affect the physical properties and performance of a HMA. These negative effects are manifested in a HMA as changes in viscosity, discoloration, and skin formation.

In order to inhibit thermooxidation and the negative effects of degradation, antioxidants are included in the raw materials and HMA formulations. This paper will discuss the thermal stabilization of Amorphous Poly-Alpha Olefin (APAO) polymer and APAO based hot melt adhesives.
