Activated Grade Zinc oxide ( superfine )
[Molecular formula] : ZnO
[Molecular weight ] : 81.37
[Uses] : Activated Zinc oxide is white or slight yellow spherical fine powder .it is yellow in high
temp,is white in low temp..Used as strength reinforcing agent of rubber or cable ,
activator( rubber ), pigment and filler of white rubber , curing agent of natural rubber &
CR. Fine granular activated Zinc oxide (size is 0.1μm ), can be used as light stabilizer of
polyolefine & PVC. or used as catalyst
[Advantage]: The dosage of Activated Zinc oxide in rubber is about 30%-40% off of common Zinc
oxide , and offer 20-30% up of tear strength, wearability, etc.

Pharmaceutical Grade Zinc oxide
[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.
[Packing]:plastic lined woven bag or kraft bag 25kg, kraft bag 20kg, 500kg ( packing), 800kg bag
or following your demands.
