Ensinger PEI
Eastman Permalyn™ 8120 Rosin Ester
Categories: Polymer

Material Notes: Product Description: Permalyn™ 8120 is a pentaerythritol ester of rosin which has been chemically modified to have a ring and ball softening point near 120°C. Permalyn™ 8120 has lower color, better color stability higher heat stability, and higher softening point than typical pentaerythritol rosin esters. It is potentially useful in hot melt adhesive and ink applications where a high softening point is desirable and especially in packaging hot melt adhesives where color and viscosity stability at application temperatures are critical.

Application/Uses:

  • Hot Melt Adhesives
  • Packaging
  • Pressure sensitive adhesives
  • Tapes and Labels
Key Attributes:
  • Excellent heat stability
  • High softening point
  • Low color
  • Superior adhesion
