Technical Document
Glycerol Hydrogenated Ester Rosin is a chemically modified form of rosin, produced by esterifying hydrogenated rosin with glycerol. The hydrogenation process reduces the double bonds in the rosin, making it more stable and less prone to oxidation. The resulting ester is a pale, thermoplastic resin with enhanced adhesive properties, improved stability, and a lower acid value compared to unmodified rosin. Its structure features a balance between rigidity and flexibility, offering desirable performance characteristics in various formulations. Glycerol Hydrogenated Ester Rosin is typically supplied in solid form, often as flakes or pellets.
