Calcium Stearate
Calcium stearate is a waxy material with low solubility in water, unlike traditional sodium and potassium soaps. â?¦ In paper production, calcium stearate is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard making. Calcium stearate is a carboxylate salt of calcium, classified as a calcium soap. The salt is a component of some lubricants, surfactants, as well as many foodstuffs. It is a white waxy powder. Calcium Stearate is an odorless, soft, fine fluffy free flowing waxy powder with low solubility in water. It is recognized as physiologically safe and is insoluble in most solvents. Compared to waxes, it has a relatively high softening point and consequently do not become greasy at high temperature. Uses and Application- Calcium Stearate is primarily used as acid scavenger, release agent and lubricant in the plastic industry. It is used for water proofing in Construction. Used as an anti- caking additives in pharmaceuticals and cosmetics. It is used as release aid and adhesion prevention in rubber industry. It is also used as a thickening agent, anti tack and Gelling Agent. It is also used as a flow agent and surface conditioner in production of certain foods.
Calcium Stearate is primarily used as an acid scavenger, release agent and lubricant in the plastics industry, for waterproofing in construction, and as an anti-caking additive in pharmaceuticals and cosmetics. In addition, our Calcium Stearate is designed to withstand exceptionally high temperatures.

Hello sir , Dhruv here From Dhruv sales corporation We are own stearate baze products manufacturing unit Zinc Stearate ,calcium stearate ,magnesium stearate and all stearate we are produce So in this case if you need any product so you can contact me sir on this email Or by other case My whats app number is :+918866617013 Ok sir Thanks
Calcium Stearate is used in the manufacture of PVC. It acts as an external lubricant in PVC processing. It promotes fusion and has a reasonable stability to heat. Calcium Stearate is used as thickening agent for lubricating grease. Calcium Stearate reduces extruder pressure build-up of rigid PVC compounds when used as a processing aid during the manufacture of pipe, siding and injection molded fittings.
White powder, insoluble in water, cold ethanol and ether, dissolved in hot benzene, benzene and turpentine and other organic solvents, slightly soluble in hot ethanol and ether. Property: Calcium stearate appearance of fine white, fluffy powder, creamy feel, soluble in water, toluene, ethanol and other organic solvents. Calcium stearate is a good non-toxic heat stabilizers and lubricants, but also adhesives, paint plain agent and waterproofing agent in the plastics and rubber chemical production process widely used. Thermal stability as effective as barium stearate, lead stearate, tin stearate and cadmium stearate. But cheap, low toxicity, good processing performance. Zinc soap and an epoxy compound with a synergistic effect, can improve the thermal stability. Commonly used in non-toxic food packaging films, medical devices and other requirements of soft products. Also widely used as the polyolefin, polyester reinforced plastics, phenolic resins, amino resins and other thermosetting plastics lubricant and release agent.
