General Description
Calcium Stearate is a calcium salt of stearic acid, supplied as a fine white powder with excellent lubricating, water-repellent, and stabilizing properties. It is widely used as a processing aid and functional additive in polymer, rubber, construction, pharmaceutical, and personal care applications. The product acts as an internal and external lubricant, improving process efficiency and surface quality in finished products.
Due to its hydrophobic nature and chemical stability, Calcium Stearate provides effective moisture resistance, improved dispersion, and controlled release characteristics. Its non-toxic profile and compatibility with a wide range of materials make it a preferred choice in applications requiring consistent performance, enhanced durability, and ease of processing.
