This product is a mixture of saturated and unsaturated fatty acid zinc, non-toxic, insoluble in water, difficult to dissolve in ordinary organic solvents, soluble in mineral oils, fats, and halogenated hydrocarbons.
This product is the best physical plasticizer for natural rubber, a multi-purpose rubber processing aid. and has both internal and external lubrication and dispersion functions. And it can improve the processing technology of rubber, enhance the qualification rate and dimensional stability of rubber products. The mixing process of rubber can promote the dispersion of fillers and other additives, shorten the mixing cycle, reduce mixing energy consumption, and lower the heat generation and mixing viscosity of the rubber material. Used in rubber processing. it can improve extrusion speed and the smoothness of' semi-finished products. When applied to vulcanized rubber, it can improve the anti-vulcanization and heat resistance of the vulcanized rubber. as well as enhance its hardness and wear resistance
When used as a uniform dispersant, it is generally suitable to add it in the early stage of rubber mixing. When used as a physical plasticizer and homogenizer, it is generally suitable to add it in the later stage of mixing, with a dosage of 1% to 3%
