CAS 1592-23-0 Calcium Stearate Powder

Description of Calcium Stearate powder：

Chemical property

At room temperature, calcium stearate powder has no significant chemical reaction with common acids, bases, salts, and other substances, showing good chemical stability.

Physical property

The physical properties of calcium stearate powder include density, granularity, fluidity, and so on. Its specific gravity is about 1.08; the particles are delicate and quickly dispersed. In addition, calcium stearate powder also has good fluidity and is easy to transport and operate during the production process.

Thermal stability

Calcium stearate powder has good thermal stability and can be used at high temperatures. Calcium stearate powders do not undergo significant decomposition or oxidation within the usual temperature range. However, prolonged high-temperature conditions may affect its performance.

Hygroscopicity

Calcium stearate powder absorbs vital water and can drink water in the environment. Therefore, attention should be paid to moisture during storage and use to avoid affecting its performance.

Lubricity

Calcium stearate powder has excellent lubricity, which can reduce the coefficient of friction, reduce mechanical wear and conflict, and improve mechanical efficiency. This characteristic makes it widely used in lubricants, antiwear agents, and other fields.

Toxicity safety

Calcium stearate powder is a low-toxic substance with no apparent harm to the human body and the environment. However, prolonged high exposure may cause skin and respiratory irritation, so it is recommended to take appropriate protective measures during production, use, and storage.

Production Method of Calcium Stearate powder：

Raw material preparation

Raw materials to produce calcium stearate powder include stearic acid and calcium hydroxide or calcium oxide. Stearic acid can be used as industrial

or food-grade stearic acid, and calcium hydroxide or calcium oxide is usually used as commercially available reagent-grade products.

Reaction process

Stearic acid is mixed with calcium hydroxide or calcium oxide in a particular proportion, usually by ball milling or stirring. It is necessary to control 

the temperature and mixing speed during the mixing process to ensure the raw materials are thoroughly mixed.

Add an appropriate amount of water or other solvents to the mixed raw materials to form a uniform solution. The solution is then heated, usually

in a water bath or an oil bath. During heating, stearic acid reacts chemically with calcium hydroxide or calcium oxide to form a calcium stearate precipitate.

Filtration and drying

The reaction product is filtered to remove unreacted calcium hydroxide or calcium oxide and other impurities. The cake is then dried to remove water and

volatile components. Attention should be paid to controlling temperature and humidity during the drying process to prevent deterioration or caking of the product.

Grinding and packingThe dried calcium stearate powder was ground to make its particle size finer and distribution more uniform. Finally, the ground calcium stearate powder ispackaged for use.

It should be noted that the specific production methods and process parameters may vary according to different manufacturers and product requirements. In the production

process, it is necessary to adjust and optimize according to the specific situation and pay attention to the control of raw material quality, reaction conditions, product quality,

etc., to ensure that the production of calcium stearate powder meets the requirements.

Shipping and Packing of Calcium Stearate powder:

Many types of packing are available depending on the Calcium Stearate powder quantity.
Packing of calcium stearate powder: 20kg per bag, then placed on pallet.
Calcium Stearate Powder Shipping: Could be sent out by air or sea as soon after receipt of payment.
