　　Zinc content, %17.5～20.0

　　Water-soluble zinc salt, %≤0.05

　　Properties: Off-white or light yellow powder, odorless and bitter. The density is 1.63～1.64g/cm3. Melting point above 300℃ (decomposition). Soluble in acetone, hexanol, slightly soluble in water, benzene, gasoline. Non-toxic.

　　Uses: Anti-aging agent MBZ is mainly used as anti-aging agent for rubber. Its performance is similar to that of anti-aging agent MB, but it improves some of the disadvantages of anti-aging agent MB, such as reducing the unstable effect of latex, prolonging and maintaining its action time, and using thiazole accelerators to prevent copper damage. This product is weak when used alone, and can increase its effectiveness when used with other anti-aging agents. The anti-aging agent MBZ is a good auxiliary heat sensitizer in latex and a good gelling agent. The dosage is 2 servings.

　　Packing: composite paper bag lined with plastic film bag, net weight 25 kg.
