Industri Grade Zinc Oxide for Synthetic Rubber 99.8% Purity

Industri grade zinc oxide for synthetic rubber 99.8% purity

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.
