Zinc stearate is a white light fine powder, insoluble in water, ethanol, ether, soluble in hot ethanol, turpentine, benzene and other organic solvents and acids. Zinc stearate is heated and dissolved in organic solvents, and becomes a jelly when cooled, and is decomposed into stearic acid and corresponding zinc salts when confronted with strong acids. Lubricity, hygroscopic, non-toxic, slightly irritating, pollution-free, no danger characteristics.
Zinc stearate is mainly used in the plastics and rubber industry, where it is used as a release agent and lubricant due to its good compatibility.

Use of zinc stearate products
1. Used in pharmaceutical industry, curing oil and lubricant preparation, also used as paint desiccant
2. Used as a stabilizer for PVC plastic products and a softener for rubber products
3. Used as softening lubricant for rubber products, polish agent for textiles, stabilizer for polyvinyl chloride plastics
4. Used in petrochemical industry polyethylene, polystyrene, polyvinyl chloride and high-grade chemical fiber masterbatch dispersant, heat stabilizer. Used for masterbatch (granules) as heat stabilizer, dispersant, lubricant.
5. It can also be used as a lubricant for styrene resins, including polystyrene, ABS and SAN resins, and as a release agent for transparent products. In the rubber industry, this product can be used as a lubricant and film separator (anti-sticking) for rubber materials. Besides. It can also be used as polishing agent for textiles, smoothing agent for paints and cosmetic ingredients.
6. Metal soap powder. For the creation of powder, powder, etc. It is mainly used as an adhesive of fragrance powder to increase the adhesion of fragrance powder on skin. Zinc stearate is light and soft, which is coated in other powders when added to powder cosmetics, so that the powder is easy to permeate. The amount of addition is generally 5%-15%.
7. Anti-foam agent. Light and heat stabilizers. Paint polishing agent and abrasive agent. Small foot drying lubricant and spacer. Stabilizer, defilm agent, lubricant for plastic products. Waterproof agent for concrete, brown asbestos, paper and fabric. Used in cosmetics and ointments.
Application areas of zinc stearate
1. Used in pharmaceutical industry, curing oil and lubricant preparation, also used as paint desiccant. Used for the processing of PVC and rubber non-toxic products, with calcium stearate, barium stearate synergistic effect, can effectively improve the photothermal stability of PVC and rubber products, PVC processing dosage is usually. 1 portion; Used for rubber products touch agent, also used for PP, PE, PS, EPS polymer additives and the manufacture of pencil lead, the general dosage is 1 to 3 parts.
2. Zinc stearate can be used as heat stabilizer; Lubricants; Grease; Accelerant; Thickener, etc. For example, it can generally be used as a heat stabilizer for PVC resin. For general industrial transparent products; Used with calcium soap, can be used for non-toxic products, generally used for soft products, but in recent years has begun to use hard transparent products such as mineral water bottles, water pipes and other products, this product lubricates well, can improve the phenomenon of scale precipitation, can also be used as a lubricant, release agent, and paint smooth agent, coating additive.
