Barium stearate is mainly used as a thermo-stabilizer of polyethylene and polyvinyl chloride copolymer, as well as lubricant. There is excellent heat-resistant stability, oilness and processibility for polyvinyl chloride products such as transparent film, leatheroid, hard plate material and tubing. It also can be used for high-temperature resistance, taking off and touching agents and machinery high-temperature lubricant. The method for producing barium stearate is mainly the traditional saponification metathesis process. This method has technical maturity, but water consumption is large, it uses caustic soda, and the high-concentration salt-containing wastewater quantity discharged is large, contaminating the environment. They do not meet the requirements of current energy-saving, environmental protection, and cleaner production. Another method is stearic acid, water, and hydrated barta added in advance after adding the saponification method of sodium hydroxide. The same saponification method of shortcoming. But the product is fluffy, not as saponification double decomposition.
