Calcium stearate, a fundamental component in numerous industrial processes, is characterized by its specific chemical composition and advantageous physical properties. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality calcium stearate, allowing manufacturers to harness its benefits effectively. Understanding these core aspects is crucial for optimizing its application in plastics, food, cosmetics, and other sectors.

Chemically, calcium stearate is an organic compound with the formula Ca(C18H35O2)2. It is essentially the calcium salt of stearic acid, a saturated fatty acid. This composition gives it unique properties that differentiate it from other stearates and additives.

Physically, calcium stearate typically appears as a fine, white, waxy powder. It is known for its insolubility in water and most common organic solvents like ethanol and ether. However, it exhibits solubility in hot organic solvents such as benzene and turpentine, which is relevant for certain formulation processes. Its non-toxic nature is a critical characteristic, making it safe for use in food-grade applications and consumer products.

Key properties that make calcium stearate so valuable include its thermal stability, meaning it can withstand high processing temperatures without decomposing. This is paramount for its function as a heat stabilizer in plastics. Its lubricating properties are also significant, reducing friction during manufacturing and improving flow. Unlike simple waxes, its higher softening point ensures it doesn't become greasy even at elevated temperatures.

Other notable characteristics include its effectiveness as a release agent, its role as an acid scavenger, and its hydrophilic nature, meaning it can absorb moisture from the air. When combined with basic lead salts in rigid plastics, it can accelerate gelation speed. NINGBO INNO PHARMCHEM CO.,LTD. ensures that the calcium stearate we supply adheres to high purity standards, maximizing these beneficial properties for our clients. By understanding the chemical composition and key characteristics of calcium stearate, industries can better leverage its versatility and efficacy.
