Zinc Stearate<\/strong><\/p>\n

Chemical Formula:<\/strong> Zn[CH3(CH2)16COO]2<\/p>\n

Melting Point:<\/strong> 117-125\u00b0C<\/p>\n

Properties:<\/strong>
Zinc stearate is a white granular or fine powder with a smooth texture and a slight fatty odor. It is non-toxic, insoluble in water and ethanol, and decomposes into stearic acid and the corresponding zinc salt when exposed to strong acids.<\/p>\n

Main Applications<\/strong><\/h3>\n
    \n
  • Zinc stearate is used as a PVC heat stabilizer. When combined with calcium stearate and barium stearate, it exhibits a synergistic effect, effectively enhancing the stability of PVC products.<\/li>\n
  • It serves as a processing lubricant and mold release agent, reducing plastic processing difficulty and improving efficiency.<\/li>\n
  • Zinc stearate is also used as a sanding aid in wood coatings, enhancing sanding efficiency in later stages.<\/li>\n
  • In petrochemical applications, it acts as an acid scavenger, absorbing excess acidic substances to protect equipment from corrosion.<\/li>\n<\/ul>\n

    Product Applications<\/strong><\/h3>\n
      \n
    1. Halogen absorber in petrochemical applications.<\/li>\n
    2. Lubricant and mold release agent for thermosetting plastics, such as amino molding compounds and unsaturated polyester resin molding compounds.<\/li>\n
    3. Stabilizer and lubricant in PVC products.<\/li>\n
    4. Dispersant and lubricant in masterbatch production.<\/li>\n
    5. Anti-sticking agent in rubber products.<\/li>\n
    6. Waterproofing agent in textiles.<\/li>\n
    7. Sanding aid for oil-based resins.<\/li>\n
    8. New granular zinc stearate formulation solves dust issues in certain industries, reducing raw material loss.<\/li>\n<\/ol>\n

      Packaging & Storage<\/strong><\/h3>\n
        \n
      1. Packed in composite paper bags lined with high-pressure polyethylene film, 20 kg per bag, or customized according to customer requirements.<\/li>\n
      2. Stored and transported as a non-hazardous material. Keep in a cool, ventilated place and avoid storage with acids, alkalis, or corrosive substances.<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
