Pentalyn™ H-E ester of hydrogenated gum rosin is a medium hard, pale, thermoplastic resin designed primarily as a tackifying resin for various types of polymer and elastomer-based adhesives. It is a pentaerythritol ester of a rosin that has been stabilized by hydrogenation. In adhesive formulations, it contributes improved resistance to oxidation, greater heat stability, better retention of colour, and greater retention of tack-imparting properties than ordinary rosin ester resins.


  • Excellent resistance to oxidation
  • High softening point
  • Light color
  • Low odor
  • Thermoplastic hydrogenated resin
  • Wide solubility and compatibility range
