Cerium Stearate, identified by its CAS number 10119-53-6, is a versatile chemical compound with a range of beneficial properties, making it a sought-after additive in several industrial sectors. Primarily functioning as a heat stabilizer for PVC, it also exhibits utility as a waterproofing agent for textiles and a drying agent for paints. For businesses looking to buy Cerium Stearate, understanding its chemical characteristics and application potential is key. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier in China, is committed to providing high-purity Cerium Stearate that meets stringent industry demands.

Chemical Properties and Characteristics

Cerium Stearate typically presents as a fine white powder. Its solubility profile is notable: it is insoluble in water but exhibits slight solubility in hot ethanol and is readily soluble in organic solvents such as hot benzene and turpentine. This solubility behavior is advantageous for incorporation into various formulations. Upon cooling, it may precipitate and can absorb moisture from the air. Critically, when it encounters strong acids, it decomposes into stearic acid and corresponding rare earth salts, a behavior formulators must consider during handling and processing.

Its molecular formula is often cited as C54H105CeO6 or Ce(C17H35COO)4, with a molecular weight of approximately 990.524. The purity standard commonly offered is 99.5%, ensuring consistent performance across applications. These properties collectively position Cerium Stearate as a reliable additive for demanding industrial processes.

Primary Applications: PVC Stabilization

The most significant application of Cerium Stearate is its role as a novel heat stabilizer for PVC. It is particularly valued for its ability to produce transparent, semi-transparent, and opaque PVC sheets, plates, soft products, and films. Its effectiveness lies in preventing polymer degradation during high-temperature processing, thereby enhancing the mechanical properties, clarity, and longevity of the final PVC products. This makes it a superior alternative to some older, less environmentally friendly stabilizers.

Secondary Applications: Textiles and Paints

Beyond its primary role in plastics, Cerium Stearate serves effectively as a waterproofing agent for textiles. By forming a hydrophobic layer on the fibers, it imparts excellent water repellency to fabrics, making it suitable for technical textiles and performance wear. Additionally, it functions as a drying agent in paints and coatings, catalyzing the oxidative polymerization of drying oils to accelerate curing and improve film hardness.
