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 will enable an optimum blend of good cohesion, processability, low odor, and thermal stability. However, finding a polymer that helps a formulation excel at all 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 with 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.

Aerafin benefits:

  • Excellent thermal stability
  • Compatibility with a wide range of hydrocarbon tackifying resins
  • Good adhesion with excellent peel strength
  • In formulation, enables a robust adhesive system with a broad processing window and sprayability
  • Low color and odor
  • Reliable global supply
