【molecular formula】: ZnO
【molecular weight】: 81.37
【Usage】: activated zinc oxide is white or light yellow sphericity minuteness powder. it is yellow when temperature is high, white when cold.
【advantages】:
1.activated zinc oxide is usde in rubber products and can save30%-40% compared with general zinc oxide.
2. desulfurizers with specific surface area can be produced in industrial desulfurizing and are sold to Germany.
