Stearic acid, or octadecanoic acid, is produced by the hydrolysis of oils and fats and is mainly used in the production of stearates. It is white waxy transparent solid or slightly yellow waxy solid. Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films. It is a PVC heat stabilizer with good lubricity and better light and heat stabilization. In plastic PVC pipes, stearic acid helps prevent "coking" during processing, and is an effective heat stabilizer when added to PVC film processing, as well as defending the finished film from discoloration caused by exposure to sulfide.
