Polymerized Rosin 95 AJ22 For adhesive tapes it enhances tackiness and cohesive strength
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.

Product Overview:
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.
II. Product Advantages:
1. High molecular weight and elevated softening point enhance adhesive retention and cohesion in tape applications.
2. Superior oxidation resistance, gloss retention, and anti-crystallization properties compared to natural rosin.
