Core features of the product

- Recognized as a low toxicity organic tin stabilizer, it can be used for food contact grade PVC products;

- Excellent lubrication performance, good transparency, no sulfurization pollution, and less prone to frost deposition;

- The initial coloring is relatively large, and the long-term thermal stability is weaker than that of mercaptan methyl tin;

- Often compounded with barium cadmium stabilizers and other organic tin compounds to produce synergistic stabilization effects;

- It can also be used as a catalyst for the condensation reaction of polyurethane and room temperature vulcanized silicone rubber (RTV).

Specification of CAS 3648-18-8 Dioctyltin dilaurate

Main application 

1) PVC industry (core use)
