Calcium Stearate is a carboxylate calcium compound, categorized as calcium soap or ordinary called calcium soap, because of its slippery properties and physical properties like soap.

Calcum Stearate is produced by reacting stearic acid with calcium oxide in certain temperature and with a certain duration of time.

Calcium Stearate is smooth and slippery to the touch, insoluble in water and can not even mix with water or waterproof / waterproof, very stable in conditions high temperature, serves as a lubricant, stabilizer and thickener in various processes.

In the manufacturing industry, Calcium Stearate is widely used as a raw material for manufactures various types of products and applications

Here are some functions and uses of Calcium Stearate in several industries;

# Foods, Pharmaceuticals & Cosmetic Industries: Calcium stearate, is the calcium salt of acid stearate derived from vegetable fats and oils, with the chemical formula Ca(C18H35O2)2. is synthetic material that can be used as a surface conditioner, anti-caking agent, release agent, lubricants, binders, emulsifiers and thickeners in foods with the European food additive number E470a. It can also be used in cosmetics, pharmaceuticals, pharmaceuticals and other applications.

Calcium Stearate is used in cosmetic, pharmaceutical, food and other chemical formulations as an anti-caking agent due to its lubricating and water-repellent properties. Calcium Stearate is used for prevent the product from absorbing moisture and stickiness as well as increase the plasticity. Addition Calcium stearate also provides a more even product yield.

# Rubber Industries: in the Rubber Industry, Calcium Stearate is used as a filler and as an anti-caking agent to prevent rubber coagulation/clumping and to release the final product from the mould.

# Plastic Industries: Calcium Stearate is an excellent solid lubricant for use in the process of injection and extrusion of various types of plastic. Calcium Stearate also functions as a stabilizer and to obtain better transparency properties, good color resistance, good long-term stability and provides resistance to weather conditions.

In the manufacture of PVC, Calcium Stearate or Calcium Stearate neutralizes hydrochloric acid, HCl, which can be released from the PVC melting process, so that it can extend the lifetime of the PVC.

Calcium Stearate is used in the following types of plastics, namely;
Acrylonitrile Butadiene… (ABS)
Polypropylene (PP)
Poly Vinyl Chloride (PVC)
Polyethylene (PE)
Polyamide (PA)
Polystyrene (PS)
Sheet and bulk molding (SMC/BMC)

Calcium Stearate as a Separating Agent for Rubber, Plastics and Ceramics
Unlike other separators, calcium stearate has a high melting point, so it can used like graphite which acts as a dry lubricant.
Some industries that use calcium stearate as a separator are:
Metal Industry, Rubber Industry, Plastic Industry, and Ceramics

Water Repellent Agent on Construction Materials
Small addition of calcium stearate in solids or emulsions in small proportions, between 1% and 6% to cement, significantly improves the water-repellent properties of the mixture.
In this way, in addition to producing the impermeability of the mixture, the addition of calcium stearate also avoid the appearance of the effect of flowering / efflorescence.
In the precast industry, calcium stearate emulsion is widely used, while the powder form is used in the manufacture of mortar and putty.
