Description
Gum rosin
Rosin is a natural renewable resin composed mainly of various resin acids. It is melted in various organic solvents and has unique chemical activity. It is esterified, neutralized and added with double bonds, disproportionated, hydrogenated, and Polymerization, etc., can change the physical and chemical properties of rosin. Rosin can expand the application of rosin in a wide range, and is an important raw material for soap, paper, paint, rubber, resin, electrical, organic synthesis and other industries.
