Acid Stearic


Molecular formula: CH3-(CH2)16-COOH


Acid Stearic is a saturated fatty acid, specifically stearic acid, that is derived through the hydrolysis of various fats and oils. It is characterized by its long-chain structure, consisting of 18 carbon atoms. Acid Stearic is used as a low temperature lubricant and thermal stabilizer for PVC production. Acid Stearic typically presents itself in the form of prill beads.
