Product Description

zinc oxide manufacturing for Rubber, Cosmetic, Plastic, Medical

 

properties: 

1. white powder or hexagonal crystal, odourlessness, relative density: 5.606g/cm3, stable nature under normal temperature.

2. insoluble in water and alcohol, soluble in acid, alkali and ammonium hydroxide.

3. Zinc oxide is a kind of white pigment, also called zinc white. When heated, it will turn to yellow, but after cooling down, it still turn back to white.
