GLYCEROL ESTER OF
GUM ROSIN PR315
Techincal Grade
Glycerol esters of gum rosin are through the esterification of gum rosin with glycerol at elevated temperatures.
These rosin derivatives exhibit a higher softening point, lower acid value, and improved thermal resistance compared to unmodified rosins.
