It is currently the plastic heat stabilizer with the most excellent performance for the rolling, extrusion, and injection molding of hard PVC. It performs specially well in two-times processing and longtime processing due to its excellent heat resistance. Because of its high safety, it is especially applicable to food packing and other hard PVC products so as to replace other plastic heat stabilizers that have high toxicity. Because its stability is much better than other organic tin stabilizer, the relevant products have better performance. Also it is more competitive on the price than other organic tin stabilizer like Octyl tin stabilizer. So it has been widely welcomed by manly large-scale PVC-processing enterprises, becoming the key adjuvant in the processing of hard PVC.
