Sell Zinc Oxide

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.     Index name     Value     Quality index     HG/T 2572-94     　     First grade     Qualified product     Zinc oxide (ZnO), %     95~98     95-98     Moisture , %≤     0.7     0.7     Water soluble matter, %≤     0.5     0.7     Loss on ignition, %     1-4     1-4     Insoluble matter in HCl, %     0.02     0.05     PbO(as pb), %≤     0.01     0.05     Manganese oxide (as Mn), %≤     0.001     0.003     CuO(as Cu), %≤     0.001     0.003     Fineness (45μm test sieve Residue on screen ), %≤     0.1     0.4     Specific surface area ,m2/g ≥     45     35     Bulk density ,g/ml ≤     0.35     0.40
