| Product description : |
1) The product is synthesized by the advanced process called "one stage process", which has high purity, good transparence and excellent thermal stability. the quality indicators and the use effect of the products have reached or even surpassed current international higher grad parts by petrochemical professional detection. it is widely used in the fields of the palstic raw materials, the plastics masterbatch, engineering plastics and rubber particals as nontoxic thermal stabilizer and lubricant.
2)Physical and chemical properties:
white fine powder, slippery feeling, combustible, not-toxic, insoluble in water or ethanol but soluble in hot organic solvents and acids; a collidal material is formed along with the degression of the temperature after soluble in the organic solvents and it will be decomposed to stearate acid and zinc salts when reacting with strong acids.
3) There are there kind of zinc stearate for plastics: AV-A, AV, AV-1
AV-A special plastic cement grade, mainly used in the petrochemical industry (PE,PS,PVC and advanced color masterbatch etc) as a disperser and thermal stabilizer.
AV plastic grade, used in color masterbatch as a stabilizer, dispersant and lubricant.
AV-1 industrial grade, used in the plastic processing field as a lubricant and mole-releasing agent.
