Calcium Stearate (C17 H35 COO)2 Ca is is a soft, fine fluffy free flowing waxy powder. This is also said as Carboxylate of Calcium. We are manufacturing this via precipitation /Direct process using high quality stearic acid. During manufacturing, the particle size, shape, Bulk Density, and purity is closely controlled to ensure product quality & uniformity. It is insoluble in water, ether and alcohol, partially soluble in hot alcohol and very well soluble in hot pyridine. It is non toxic in nature. It is available in form of white powder. It too emits irritating fumes when heated. Extremely low solubility makes calcium stearate a very versatile substance.
PROCESSING
Through Fusion Process : Calcium Stearate made via fusion process is produced by heating stearic acid and calcium oxide. It is an insoluble salt of calcium, stearic acid and palmatic acid. It is insoluble in water, ether, acetone and cold alcohol. Calcium stearate is used as a drying lubricant and dusting agent for rubber.
Through Precipitation Process : Calcium Stearate made via precipitation process is a very light, white and fine product with minimum possible foreign heavy metals. It is higly recommended for paper products used for food packaging applications. It is also recommended for commercial paper coatings, ink applications and high quality construction chemical
Important Properties :
The important properties of our Zinc Stearate, relevant to various applications are:
- Controlled Particle Size.
- Good Dispersion.
- Low Bulk Density.
- Good melt transparency.
- Good Heat Stability & Color Stability.
- Purity to reduce extruder pressure build up.

APPLICATION
- Rubber
Used for preventing stickiness of unvulcanised Rubber & as an additive to improve flow & dispersion of Vulcanising Agents.
-
Plastics / Polymer
In plastics, it can act as an acid scavenger or neutralizer at upto - concentrations of 1000ppm, a release agent. It may be used in - plastic colorant concentrates to improve pigment wetting. Also as - acid acceptor in polyethylene, propylene, polystyrene & in ABS - Printing Ink
As a dulling agent & viscosity improver. - Lubricant
As a thickener & a lubricant in pencils and crayons. - Paints
As thickener/Flatting agent & to improve water resistance & gloss. - Metal
This is used as die Releasing Agent in Powder Metallurgy.
- Construction / Cement
The concrete industry uses calcium stearate for efflorescence control of - cementitious products used in the production of concrete masonry units - i.e. paver and block, as well as waterproofing.
- Textile
As water Proofing Agent - Agro Chemical
Anti caking agent in Pesticides. - Pharma
Applications in the personal care and pharmaceutical industry includeing tablet mold release, anti-tack agent, and gelling agent. - We can provide the material as per Customer/Buyer specification & requirement.
