Zinc stearate for plastics

Description:

The product is adopted the newest international process for clean production, which is energy-saving and pollution-free. It possesses advantages of low free fatty acids, high purity, good transparence, excellent thermal stability and outstanding properties.

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/cm^3. 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.
