Pentaerythritol Ester of Hydrogenated rosin

This series ester is made from hydrogenated rosin through esterification with pentaerythritol; To compare with ordinary rosin ester, it can improve resistance to oxidation, greater heat stability, better retention of color, and greater retention of tack-imparting properties.

Applications:

1. Adhesives and sealants based on natural rubber, chloroprene rubber, SBR, SBS, SIS, EVA, polyolefins (APO, APAO), etc.

2. Hot melt adhesives and Pressure sensitive adhesives (hot melt or solvent based), contact glues.

Specifications:

Properties：

1. High softening point，Low odor

2. Wide solubility and compatibility range，Compatible with UV acrylic adhesives

3.Excellent resistance to oxidation

Solubility:
