Organotin Stabilizer
Organotin Stabilizers are high-performance PVC heat stabilizers based on methyltin, butyltin, or octyltin compounds, delivering superior thermal stability and excellent transparency for demanding rigid PVC applications. They are particularly effective in clear PVC bottles, rigid pipe, and profiles where outstanding initial color and long-term stability are critical. Certain octyltin grades are approved for food-contact rigid PVC applications.
