Composition: A mixture of saturated and unsaturated fatty acid zinc soaps Properties: This product is non-toxic, insoluble in water, sparingly soluble in most common organic solvents, and soluble in mineral oils, fats and halogenated alkanes Indicators: Appearance: Light yellow granules Melting point ℃: 75-85 Zinc oxide content %: 12-14 Iodine value gl/100g: 40-50 Ash content %: 12-14 Uses: This product is the best physical plasticizing peptizer for natural rubber, and is a multi-purpose rubber processing aid. When applied to rubber, it can improve the reversion resistance and heat resistance of vulcanized rubber, and has internal and external lubrication and dispersion functions. It can be used in the mastication and mixing processes of natural rubber and synthetic rubber. When used for rubber mastication, it can peptize natural rubber and isoprene rubber. This product has excellent compatibility with rubber, does not bloom, and has dual functions of peptization and lubrication. It can improve rubber processing technology, increase the qualification rate and dimensional stability of rubber products, reduce energy consumption, and improve mixing efficiency. In the rubber mixing process, it can promote the dispersion of fillers and other additives, shorten the mixing cycle, reduce mixing energy consumption and reduce rubber compound heat generation. Used in rubber processing, it can improve the extrusion performance of rubber compounds, increase extrusion speed and smoothness of semi-finished products. Dosage: 1-5%.
