Polymeric rosin pentaerythritol ester
Polymeric rosin pentaerythritol esters are a group of polymeric rosin-modified thermoplastic resins. They are produced from polymeric rosin manufactured via the sulfuric acid process as a base material, through refining, esterification, and stabilization processes. They exhibit excellent color stability and aging resistance, a high softening point, good compatibility with polymeric materials, significant tackifying effects, and rapid drying. They meet the specific needs of the adhesive, coating, and ink industries, and are particularly suitable for formulating adhesives and inks requiring a high softening point.
Product Features:
Good heat resistance
High softening point
Good oxidation resistance
Extremely light color
Low odor
