Dioctyltin oxide, DOTO

Dioctyltin oxide (CAS 870-08-6) is a highly effective PVC heat stabilizer, suitable for rigid transparent products, offering excellent heat resistance and transparency, and is free from sulfur contamination. It also catalyzes the synthesis of polyester resins, aiding in the curing of coatings and adhesives; it serves as an organotin intermediate for the preparation of derivatives such as dioctyltin maleate; and it can improve the compatibility of polymer materials with fillers, optimizing the mechanical properties of the product.
