Zinc stearate

Zinc stearate Fineness of 200 mesh 98% Index Name First Grade Qualified Grade Appearance white powder white powder

Physicochemical Properties: white fine powder, greasy feeling, can burn, non-toxic, specific gravity 1.095, melting point ≥ 118 ° C, insoluble in water, ethanol, soluble in hot organic solvents and acids. In case of cold jelly heating dissolved in organic solvents, the case of the acid decomposition of stearic acid and zinc salts.  ZS-AV11 high-purity plastic specific level; main dispersing agent, heat stabilizer used in the petrochemical industry, production of polyethylene, polystyrene, polyvinyl chloride and high-grade chemical fiber masterbatch.  Rubber parts is a good lubricant, it is the end of curing materials bonded together to effectively isolate the agent, soluble in rubber, and the last to be absorbed in the rubber vulcanization process at high temperatures than with inert material from the products better; polystyrene not only proved to be the most effective lubricant, but also, more importantly, as a valid color powder in the melt can color degradation can be avoided in the application; polypropylene can improve the dispersion of the pigment; polyethylene molding compound can improve the release effect. For the reinforced polyester premix molding can also be conducive to stripping. In addition, it is commonly used in phenolic and ABS model compound.Environment \ toxicity        Can be biodegradable; non-toxic, can refer to the U.S. Food and Drug Administration (FDA) Title 21 CFR.863-177.2600-184.1229 and ECE will be commissioned to Directive 90/128/EEC Date: February 23, 1990 and further modified.
