Konson®  Zinc Stearate for PVC heat stabilizer

Product name: Zinc stearate
Appearance: White powder
MF: Zn(C17H35COO)2
MW: 631

 Zinc stearate is a zinc soap that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene and chlorinated hydrocarbons) when heated. It is the most powerful mold release agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect. Its main application areas are the plastics and rubber industry where it is used as a releasing agent and lubricant which can be easily incorporated.

Specification :

Zinc Content %10-12
 Water % ≤0.5
Free Fatty Acid(As Stearic acid)% ≤1
Melting Point:118-125 °C
Fineness(thr 200 mesh),% ≥99.5
Ash % ≤12±1

Applications : 

PVC additive, PVC stabilizer adding in PVC products
