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.
Aerafin™ polyolefin polymers are changing that with a next generation polyolefin that enables hot-melt adhesives to be formulated to have a improved mechanical properties, best in class thermal stability, and the ability to spray at lower temperatures while delivering low odor and low VOCs the industry has come to expect from the best olefin-based hot-melt adhesives available.
