[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.
