Molecular formula ZN(C17H35COO)2, molecular framework RCOOZnOOCR (R is a mixed alkyl team in business stearic acid), flammable, particular gravity 1.095, auto-ignition aspect 900 ℃, density 1.095, melting point 130 ℃, with a slippery feeling.Insoluble in water, ethanol, ether, soluble in warm ethanol, turpentine, benzene as well as various other organic solvents and acids. Zinc Stearate Powder is heated and liquified in a natural solvent to create a gel when cooled down, and decayed into stearic acid and also equivalent zinc salts in the existence of strong acid. It is oiling, hygroscopic, safe, somewhat bothersome, non-polluting and non-hazardous. Zinc stearate and calcium stearate can be divided by utilizing the residence that zinc stearate is soluble in benzene as well as calcium stearate is insoluble in benzene.

Zinc stearate is insoluble in polar solvents, yet really soluble in aromatics and additionally chlorinated hydrocarbons when heated up.Their main field of application is the plastics as well as rubber industry, where they are utilized as release representatives and also lubricants as a result of their great compatibility.

The general dosage is 1-2%, yes, the excess is easy to spray. In addition, zinc stearate has the effect of reducing the surface gloss of rubber products and has a certain matting effect. You can also add 1-2% during mixing, which can significantly change the fluidity of the rubber compound, that is, the internal addition of the rubber fluidity modifier, which can significantly reduce the occurrence of material shortages and defective products in the production of film-pressed products.

3. The relative density of Zinc Stearate Powder is 1. It is mainly used as active agent and dusting powder at 0.5-1.10. It can be used as mold release lubricant, plasticizer and softener, and is suitable for natural rubber. When used as an active agent, it can act as an acid-type activation and change the processing performance.

That is, before cutting the raw silicone strip with a knife, you can put the paste zinc stearate (a little) into an appropriate amount of tap water, and then blow and mix it with a steam pipe (because zinc stearate is a insoluble in water). Then you can put the cut raw rubber strips into the water and take them out immediately, without sticking to each other at all. You can also put this water in the spray cheeks and spray while cutting the glue.

Zinc Stearate Powder is a relatively common material in industrial production, but in actual life, everyone does not know much about this product.
