About Calcium Stearate Emulsion:
Calcium stearate is an organic compound, molecular formula C36H70CAO4, white powder is insoluble in water, which can be used as waterproof, lubricants, and plastic auxiliary tools. Calcium stearate is calcium carboxylate and is divided into calcium soap. It is some lubricants, surfactants, and components of many foods. This is a white waxy force.
Calcium stearate emulsion is a stabilizer and lubricant of polychloroacetic acid, but the stable effect is poor, long-term thermally stable effect is good, and non-toxic food packaging, medical device and other soft film vessels. In polyethylene, polypropylene as a halogen absorber, the catalyst in the resin can eliminate the adverse effects of resin color and stability. It can also be widely used as a lubricant of polyolefin fibers and mold plastic, or a phenolic, amino group such as a phenolic, amino group, and a polyester reinforced plastic moisturizing and release agent, a water repeater of grease, and a water repeater of textiles. Paint flat light, etc. Feel free to send an inquiry to get the latest price if you would like to buy Calcium Stearate Emulsion in bulk.

How is Calcium Stearate Emulsion produced?
Preparation of calcium stearate emulsion by saponification synthesis method
Add the CaCl solution and the NaOH solution to the reactor according to the stoichiometric ratio, then add the dispersant, emulsifier A, emulsifying aid and CMC under agitation, and then mix evenly to obtain an emulsion; add stearic acid and catalyst to the emulsion, and keep the temperature constant Stir to obtain a mixed solution; stearic acid and calcium hydroxide react to form calcium stearate, which is uniformly dispersed in the emulsion. Finally, n-octanol and modified polyvinyl alcohol aqueous solution (mass percentage concentration is 10%) are added and stirred to react 0.5- 20s, quickly cooled to room temperature, high-speed shear dispersion for 10-30 minutes to obtain calcium stearate emulsion, and its solid content, viscosity, dispersibility, etc. were analyzed and determined.
Calcium Stearate Uses
Calcium stearate is mainly used as an acid scavenger, release agent and lubricant in the plastic industry, used in building waterproofing, and used as an anti-caking additive in medicines and cosmetics.
1. Calcium stearate emulsion is a stabilizer and lubricant of polychloroacetic acid, but its stabilizing effect is poor, and the long-term thermal stabilization effect is still good. It can be used as non-toxic food packaging, medical equipment and other soft film utensils.
2. Calcium stearate emulsion is used as a halogen absorbent in polyethylene and polypropylene, which can eliminate the adverse effect of the residual catalyst in the resin on the color and stability of the resin.
3.Calcium stearate emulsion can also be widely used as a lubricant for polyolefin fibers and molded products.
4. Calcium stearate emulsion can be used as a lubricant and release agent for phenolic, amino and other thermosetting plastics, polyester reinforced plastics, and a thickening agent for grease.
5. Calcium stearate emulsion is used as a waterproofing agent for textiles and a smoothing agent for paints.
