Rosin Esters

The excellent adhesion performance and compatibility

FOREVEREST^® Rosin Esters are the series of ester gum based on rosin carboxyl modifying. Through the esterification processing, in a high temperature (180~300°C) and a long time (6~11 hours) reaction with high activity catalysts, the rosin esters have excellent performance on acid resistance, alkali resistance, and thermal stability.

Now a day, 60% of modified rosins are rosin esters, which have used as the weighting agent for beverages, plasticizer for gum based and coated fertilizer of tobacco.

Rosin esters have excellent adhesion performance and compatibility, the industrial is specialty applied for EVA based hot melt adhesives and HMAPSA in packages, labels, tapes, sanitary napkins, diapers, and bandages.
