Detailed Description
Product quality technical indicator
Name: zinc stearate
Molecular formula: Zn(C17H35COOH)2
Molecular weight: 631
White fine powder, slippery feeling, combustible, non-toxic and density is 1.095g/cm3. It is not dissolved in water or ethanol but soluble in the organic solvents and acids. After heating and dissolving in organic solvent, it will be become colloidal material under cooling condition; it will be decomposed to stearic acid and zinc salts when reacting with strong acids.
Application:
1. For PVC hard products: used as stabilizer and lubricant, it can accelerate the gelatin speed together with the basic lead salt and lead soap.
2. For PE and PP: used as halogen absorbing agent, it can eliminate bad effects of residual catalyst on resin’s color and stability.
3. For polyolefin fiber and plastic model product: used as lubricant and mold-releasing agent.
4. For rubber processing: used as mold-releasing agent, plasticizer, intensifier for lubricating grease, water-proof agent for textiles, flatting agent for pain industry, etc.
5. Also can be used in food additive, feed additive and cosmetics.
