Calcium Stearate, identifiable by CAS 1592-23-0, functions as a highly effective internal lubricant and acid scavenger used primarily to facilitate the processing of rigid PVC and polyolefins. Chemically defined as the calcium salt of stearic acid , this fine, white, water-repellent powder serves as a mold release agent in rubber molding and a waterproofing additive in cementitious materials. The substance, often referred to as Calcium Distearate or Calcium Octadecanoate in technical formulations, acts as a secondary stabilizer in halogen-containing polymers, neutralizing acidic residues to prevent degradation. We facilitate bulk supply of this metallic soap with competitive factory pricing, capable of meeting customized specifications for particle size (mesh) and free fatty acid content, backed by comprehensive MSDS, TDS, COA documentation.

Usage
As a heat stabilizer for polyvinyl chloride and lubricant for various plastic processing, mold release agent, etc. In hard products, it can be combined with basic lead salts and lead soap to improve the gelation speed. It is also used in food packaging, medical instruments and other non-toxic soft films and utensils. It can also be used as a halogen absorber for polyethylene and polypropylene to eliminate the adverse effects of residual catalysts on color and stability. It is used as a plasticizer in rubber processing, which can soften natural rubber and fully finished rubber, and has almost no effect on vulcanization. It is also used as a lubricant for polyolefin fibers and molding compounds, a thickener for grease, a waterproofing agent for textiles, a leveling agent for paints, and a plasticizer for the manufacture of plastic records. polyethylene and polypropylene as halogen absorbents; lubricants and release agents for phenolic, amino acids and other thermosetting plastics; grease thickener; waterproof agent for waterproof fabrics; Paint flattening agent and pencil lead lubricant, etc. Food-grade calcium stearate is used as an anti-caking agent. Calcium stearate is also used in the production of pencil leads
FAQ - Technical & Supply Chain
-
Q:
Is calcium stearate used as an industrial processing aid rather than a finished consumer product?
A: Calcium stearate is typically applied as a functional additive in polymer processing systems, where it supports manufacturing operations rather than serving as a standalone end-use material. -
Q:
Is Calcium Stearate chemically synonymous with Calcium Distearate?
A: Yes, Calcium Stearate and Calcium Distearate refer to the same metallic soap identified by CAS 1592-23-0, formed by the reaction of calcium oxide with stearic acid.
