Polymerized Rosin

Using gum rosin as raw material, our polymerized rosin is processed with the new advanced Sulphuric acid and Chloride Zinc method.Its advantages as follows: high content of dimers, light color,highsoftening point and acid value, no crystal, low content of hot-water-soluble material, easily dissolves in oil, the color of the lead acetate paper changes little, etc.Mainly be used in inks, paints, rubber, adhesives, dampproof cloth, paper-making, emulsifiers, etc. Specification: TypeB-90B-100B-115B-140Appearance yellow transparent solidSoftening Point (R&B,°C)90-10095-105110-120135-145Color of glassMax 4th classMax 4th classMax 4th classMax 4th classColor (Gardner Standard)Max 10Max 10Max 10Max 10Acid value (mg/g)Max 165Max 160Min 145Min 140Density (Delivery form, 20°C, abt., g/cm³)1.08-1.11.08-1.11.08-1.11.08-1.1SlubilityWaterInsolubleInsolubleInsolubleInsolubleAlcoholSolubleSolubleSolubleSolubleAromaticsSolubleSolubleSolubleSolubleAliphaticsSolubleSolubleSolubleSolubleEsterSolubleSolubleSolubleSolubleNote: the products' specs and packing can be customized according to requirements.
