Zinc stearate is a white powder, insoluble in water, soluble in heat It contains organic solvents such as ethanol, benzene, toluene, and turpentine; it decomposes into stearic acid and corresponding salts when exposed to acids; it is a fire hazard under dry conditions, with an auto-ignition point of 900°C; it is hygroscopic.

Zinc stearate is a good release agent:

Instructions for supplying zinc stearate : Zinc stearate has good compatibility and is used as a release agent. It is mainly used as a release agent for thermoplastics and heat-fixable products, such as polyurethane foam and unsaturated polyester.

Zinc stearate is used as an internal release agent in polyurethane-reaction injection molding processing. Its mechanism is that when the two components are mixed and injected into the mold cavity, zinc stearate will precipitate. It forms a gel and migrates to the surface of the part as curing progresses, forming a thin film with high foam content at the mold cavity interface.

The application and advantages of zinc stearate as a release agent in ceramic production:

Add an appropriate amount Zinc stearate is conducive to enhancing the lubricity, easy stirring, and good dispersion of ceramic raw materials, prompting the raw materials to be fully stirred and evenly lubricated. After dry press forming, it is also conducive to successful demoulding. Zinc stearate can directly replace the functions of lubricants and release agents. Reduce costs, and the demoulding pass rate can reach more than 90%.

When adding lubricants and release agents separately, adding these two additives together may increase your costs. Improper use will also affect the chemical effects of other materials and the production procedures are complicated, which wastes manpower and time. material resources.

Practice has proven that the use of zinc stearate as a release agent has advantages in terms of price and complexity of production procedures.
