Product Description

Product Description

Calcium stearate is a white, odorless, water-insoluble powder classified as the calcium salt of stearic acid. Due to its hydrophobicity and thermal stability, it is widely used as a lubricant, stabilizer, and anti-caking agent. In plastic and rubber manufacturing, it acts as a release agent and acid scavenger, improving processing efficiency. In cosmetics, it can be used as a flow aid in tablet formulations or a thickener in powders. It is also used in foods as an anti-caking additive (E470a) and in building materials (such as concrete) to impart water-repellent properties.

Application

Applications of Calcium Stearate:
 1. Plastics Industry* Acts as a lubricant and release agent in PVC, polyolefins, and other polymers to prevent sticking during processing. 
* Used as a stabilizer to minimize degradation caused by heat and UV exposure. 
2. Rubber Industry* Acts as a release agent and processing aid to improve flow properties. 
* Prevents adhesion between rubber compounds during storage. 
3. Building Materials* Used in cement and concrete as a waterproofing additive and to reduce air entrapment. 
* Enhances the processability of gypsum products. 
4. Paints and Coatings* Acts as a flattening agent (matting agent) and stabilizer to improve texture and durability. 
5. Food Industry* Approved as a food additive (E470a) for anti-caking, emulsifying, and release properties (e.g., in candies). 
6. Paper and Packaging* Acts as a coating agent to improve water resistance and smoothness. 
7. Crayons & Pencils* Provides hardness and smooth build in wax-based products.
