Mercaptan dibutyltin is approved as a thermal stabilizer in the United States, Japan, and many European countries, permitted for use in PVC products for food and pharmaceutical packaging as well as water supply pipes. Organotin thermal stabilizers are primarily classified into three major series: butyltin, methyltin, and octyltin. Dibutyltin thermal stabilizers represent the most widely used, thermally stable, and highest safety standard stabilizer category in the current PVC thermal stabilizer industry, serving as one of the most important alternatives to lead-based thermal stabilizers. The most representative product is mercaptan dibutyltin. Hubei Benxing is a leading global producer of mercaptan dibutyltin. China has become an important global production base for organotin thermal stabilizers, while the United States was the first country to use organotin compounds as stabilizers in PVC products, with organotin thermal stabilizers accounting for over 40% of total PVC thermal stabilizer usage in the United States.
