Features of zinc stearates
1. Zinc stearates is non-toxic heat stabilizer
2. Good smoothing properties
3. Can prevent initial coloring
4. Can easily cause quick degradation,and thus use level should be strictly controlled
Application of zinc stearates
1.Rubber: It can improve flow of rubber and dispersion of vulcanising agent throught the compound.
2.Plastics :It as Internal lubricants and mould release agents for Polystyrene,Phenolics,Polyolefins,
Nylon,Melamine Master Batches and Urea.
3.Coating: Stearate zinc as a component in the coating of abrasive papers and sanding sealers.
4.PVC Compounds: zinc stearate mixture with calcium stearate,barium stearate as compound heat stabilzier.
Synthesis processing
zinc stearate powder,based on water as the medium.Synthesis by stearic acid and zinc salt.
Heavey grade zinc sterarate prepared by the reaction of stearic acid and zinc oxide direct synhtesis.
Metal stearates also called metal soaps, it is produced by the outside of the alkali metal oxides or salts and fatty acids
salts.this series product mainly inluding:sodium stearate, potassium stearate,zinc stearate,calcium stearate,
Metallic stearates, aluminium stearate, and so on,Metallic
stearates is a kind of very important industrial raw materials, can be used as heat stabilizer, lubricant, release agent, desiccant, preservatives, abrasive, precipitation agent, water repellent agent, softening agent, thickening agent, flame retardant, anti foam agent ect, widely used in plastics, coatings, textiles, construction, daily chemical, rubber, food, oil, metal processing and other industries.
