Barium Stearate PBAS 501 is a chemical compound obtained by the reaction of stearic acid and barium and is produced in the form of a white crystalline powder with a soft texture. This compound is known by the chemical formula Ba(C₁₈H₃₅O₂)₂ and is used in a wide range of industries due to its high thermal stability, resistance to light and oxidation, and effective lubricating performance.

Main Features of Barium Stearate PBAS 501

•        Excellent thermal and optical stability

•        Strong lubricating and anti-sticking properties

•        Waterproof and moisture resistant

•        White powder and insoluble in water

•        Solubility in organic solvents after heating and forming a colloidal solution after cooling

When it comes into contact with hot and strong mineral acids, it decomposes into stearic acid and barium salts, which is a significant feature in some industrial applications.

Applications of Barium Stearate PBAS 501

•        Thermal stabilizer in hard and soft PVC: Prevent thermal decomposition and increase product life

•        Lubricant in extrusion and molding processes of plastics

•        Light and heat stabilizer for plastics and rubbers
