GLYCEROL ESTER OF
GUM ROSIN PR315
FOOD GRADE
Glycerol esters of gum rosin are obtained by esterifying rosin with glycerol at high temperature.
GUM ROSIN PR315
FOOD GRADE
Glycerol esters of gum rosin are obtained by esterifying rosin with glycerol at high temperature.
These rosin derivatives have higher softening point, lower acid value and higher thermal resistence when compared to straight rosins.
