Gum Rosin
Gum Rosin is a kind of natural resin,mainly composed of various kinds of resin acids, it can be dissolved easily in many organic solvents,and has special chemical activity. So it is an important raw material for the production of paper, coating, inks,rubber,soaps,electronic industrial products,food grade ester gum,rosin ester resins etc.
