Key Characteristics and Composition

Calcium Stearate (Calcium octadecanoate, C36H70CaO4) appears as a white, fine powder, composed of particles measuring approximately 1-10 m. It is odorless, has a neutral taste, and is non-toxic, making it suitable for use in multiple industrial applications. With a high purity level of 99%, loss on drying of 0.5% max, and very low heavy metals content, its reliability and safety are assured.

Versatile Industrial Applications

Widely utilized as a lubricant, stabilizer, and release agent, Calcium Stearate serves crucial roles in the plastics, rubber, and cosmetics industries. Its physical and chemical properties enable smoother processing, improved product release, and enhanced stability during manufacturing, contributing to improved efficiency and quality of the final products.

Storage and Handling Recommendations

To ensure maximum shelf life of 2 years and maintain chemical stability, Calcium Stearate should be stored in a cool, dry environment away from moisture and heat sources. Proper storage prevents clumping and preserves the powders effectiveness throughout its usage period.

FAQs of Calcium Stearate:

Q: How is Calcium Stearate typically used in industrial applications?

A: Calcium Stearate is mainly used as a lubricant, stabilizer, and release agent in plastics, rubber, and cosmetics manufacturing. It helps to reduce friction, prevent sticking, and enhance the stability of products during processing.

Q: What benefits does Calcium Stearate offer during manufacturing processes?

A: Its ability to provide lubrication and act as an anti-caking and release agent helps in smoother processing, reduces product loss during mold release, and minimizes wear on equipment, contributing to efficient and cost-effective production.

Q: Where should Calcium Stearate be stored to preserve its quality?

A: For optimal preservation, store Calcium Stearate in a cool, dry location away from direct heat and moisture. This prevents degradation, maintains fine powder texture, and ensures its two-year shelf life.

Q: What is the recommended process for handling Calcium Stearate safely?

A: Although Calcium Stearate is non-toxic and odorless, using personal protective equipment such as gloves and masks is advisable to avoid inhaling fine powder particles. Handle it in a well-ventilated area to avoid dust accumulation.

Q: When can Calcium Stearate decompose, and what are its thermal properties?

A: Calcium Stearate has a melting point of 148-155C but decomposes before boiling. It remains stable under most industrial temperatures, but excessive heat should be avoided to prevent decomposition.

Q: What is the solubility profile of Calcium Stearate?

A: This compound is insoluble in water, but it dissolves in hot alcohol and organic solvents, which can be advantageous for processing where moisture resistance is desired.

Q: How does the fine particle size of Calcium Stearate contribute to its industrial utility?

A: The fine powder form (1-10 m) ensures consistent dispersion throughout mixtures, leading to uniform lubrication and stabilization across the processing batch.
