[Product name]: Pharmaceutical grade powdery & Granular Zinc oxide (indirect process).
[Characteristics]:
1, high purity with low impurities
2, small particles, good for drug
3, low impurities, especially for Pb, Cd, and Hg, good for reducing the bad effects of drug
4, Zinc oxide & its derivatives can improve the adhesion, solidifying time, stability,storage,
wet adhesion and performance in water and fire.
5, Granular Zinc oxide has good fluidity, it has low dust and can offer better work surrou-
nding and improve the yield. All kinds of Granule Zinc oxide are available.
