Zinc stearate 25kg

Zinc stearate is an inorganic compound composed of zinc and stearic acid. It is a fine, white powder that is insoluble in water. Zinc stearate is primarily used as a lubricant, release agent, and stabilizer in various industries, including plastics, rubber, cosmetics, and pharmaceuticals. It has excellent hydrophobic properties, which make it effective in preventing the sticking or adhesion of materials during processing or manufacturing. Zinc stearate is also used as a thickening agent, emulsion stabilizer, and anti-caking agent in certain applications.

Description

Zinc stearate has several major and common uses across various industries. Some of its main applications include:

  1. Plastics and Rubber Industry: Zinc stearate is widely used as a lubricant and release agent in the processing of plastics and rubber. It helps improve the flow properties of polymers, prevent sticking to molds or machinery, and enhance the release of finished products.
  2. Cosmetics and Personal Care Products: Zinc stearate is utilized in cosmetics and personal care products, such as makeup, powders, creams, and lotions. It acts as a binder, texturizer, and anti-caking agent, providing a smooth and silky texture while preventing clumping.
  3. Pharmaceuticals: Zinc stearate is employed in pharmaceutical formulations as a lubricant and glidant. It aids in the tabletting process by reducing friction between particles, ensuring smooth tablet compression, and enhancing powder flow.
  4. Paints and Coatings: In the paint and coating industry, zinc stearate functions as a flatting agent, preventing gloss and providing a matte or satin finish. It also acts as a rheology modifier, improving the suspension and stability of pigments and fillers.
  5. Adhesives and Sealants: Zinc stearate is used as a processing aid and anti-blocking agent in adhesives and sealants manufacturing. It prevents tackiness and sticking during processing, facilitates handling and application, and improves the overall performance of the final product.
  6. Rubber Compounding: Zinc stearate is a common ingredient in rubber compounding formulations. It acts as a dispersing agent, promoting the uniform distribution of fillers, improving rubber flow properties, and enhancing processing characteristics.
  7. Powder Metallurgy: In the field of powder metallurgy, zinc stearate serves as a lubricant during the pressing and compacting of metal powders. It reduces friction and allows for easy ejection of the compacted parts from the molds.

These are some of the major and common uses of zinc stearate, but it may also find applications in other industries such as textiles, building materials, and food packaging.

Safety Guidelines

When using zinc stearate, it is important to observe certain safety measures to ensure proper handling and minimize potential risks. Here are some safety guidelines to consider:
  1. Personal Protective Equipment (PPE): Wear appropriate PPE, including gloves, safety goggles or glasses, and protective clothing, when handling zinc stearate. This helps protect your skin, eyes, and clothing from potential contact and irritation.
  2. Ventilation: Work in a well-ventilated area or use local exhaust ventilation to prevent the accumulation of airborne dust or fumes. Ensure proper ventilation during mixing, processing, and any other activities involving zinc stearate to minimize inhalation exposure.
  3. Avoid Dust Generation: Take measures to minimize dust generation during handling or transferring of zinc stearate. This can include using dust collection systems, wetting the powder before handling, or employing appropriate handling techniques to reduce the potential for dust dispersal.
  4. Storage: Store zinc stearate in a cool, dry, well-ventilated area away from incompatible substances, such as strong oxidizers or acids. Follow proper storage guidelines to prevent the risk of fire, contamination, or degradation.
  5. Avoid Ingestion and Inhalation: Avoid eating, drinking, or smoking in areas where zinc stearate is handled. Also, refrain from inhaling the dust or mist generated during handling to prevent respiratory irritation or other health effects.
  6. Spill and Cleanup: In the event of a spill, clean up the area promptly and properly. Use appropriate methods, such as vacuuming or sweeping, to minimize dust generation. Dispose of the spilled material and cleanup waste according to local regulations.
  7. Follow Handling Guidelines: Adhere to the manufacturer’s handling instructions and safety data sheet (SDS) for specific guidance on safe handling, storage, and disposal of zinc stearate.
  8. Training and Awareness: Ensure that individuals working with zinc stearate are adequately trained on its safe handling and aware of the potential hazards associated with the substance.
Always consult the safety data sheet (SDS) provided by the manufacturer for comprehensive information on the safe handling, storage, and disposal of zinc stearate specific to the product you are using.
