Polymerized Rosin 95 AJ20 excellent oil solubility Superior oxidation resistanc

Polymerized rosin is produced through esterification with pentaerythritol. It is a yellowish-brown amorphous solid characterized by high molecular weight, elevated softening point, high purity, non-crystalline properties, high acid value, low hot water extract content, excellent oil solubility, minimal discoloration with lead acetate, and a higher softening point than natural rosin.
