Monooctyl tin oxide is the main intermediate of synthetic PVC high-efficiency non-toxic organotin heat stabilizer. The biggest characteristic of octyl tin series PVC heat stabilizer formed by reaction with isooctyl thioglycolate, lauric acid and maleic anhydride is Strong heat resistance and used on food and pharmaceutical packaging materials because it is non-toxic to human body


Monooctyl tin oxide is mainly used in the production of PVC heat stabilizers, paint enhancers, and catalysts for partial antioxidant production.
