HMA assembly

Hot-melt adhesives (HMA) for assembly  

Imagine the possibilities of a versatile, high-performance adhesive solution for assembly applications. Vistamaxx™ performance polymers use ExxonMobil’s proprietary metallocene technology to develop a new generation of high-performance HMA formulations.

Adhesives that use Vistamaxx combine it with a mix of ingredients including tackifying resins (such as Escorez™ tackifiers), wax and antioxidant. Since Vistamaxx can account for 70-90% of the mixture, it offers many competitive benefits, including high mileage and low odor.

Low viscosity, high performance

Formulating hot melt adhesives with low-viscosity grades of Vistamaxx polymers (8380, 8780, 8880) enables significant performance benefits compared to ethylene-vinyl (EVA)- and amorphous polyalphaolefin (APAO)-based formulations.

Combining two Vistmaxx grades enables formulation flexibility and property balancing.
