Stearic acid is widely used in PVC plastic pipe, sheet, profiles, film manufacturing. Is PVC heat stabilizers, with good lubricity and good light and heat stability. Plastic PVC pipe, stearic acid helps prevent the process of "coke", adding PVC film processing is an effective heat stabilizer, while the finished film is placed defensive violence caused by sulfides discoloration.
