Hot-melt adhesives with the right olefin polymer
Choosing the right polymer for hot melt adhesives can be a challenge. When evaluating polymers, the ideal product would enable the optimum blend of good cohesion, processability, low odor, and thermal stability. But finding a polymer that enables a formulation to excel at all of these performance characteristics can be difficult.
