alkyl tin oxide application of PVC heat stabilizer

This article analyzes the alkyl tin oxide PVC heat stabilizers in the application, and pointed out the  Glycerol monostearate direction of its future development.
Octyl tin mercaptide stabilizer system class with excellent high temperature stability and long-term dynamic stability chroma, it plasticizing effect of the resin and mixed metal salt or lead salt stabilizer compared to produce a lower melt viscosity, it is preferably of rigid PVC processing stabilizer, it will not happen fouling, the  antimony trioxide reduced equipment cleaning time, the disadvantage is scented, light stability is poor, the presence of a metal, easy to cross coloring.
At present, China's thermal stabilizer varieties not only single, and the performance is relatively poor, relatively large gap with foreign countries, has seriously affected the  black iron oxide development of China's PVC processing industry. The organic tin heat stabilizer for its excellent performance will gradually replace traditional lead salts and metal soap heat stabilizers. Therefore, the development of low cost, high yield alkyl tin oxide (especially octyl tin oxide) and process for the synthesis of PVC heat stabilizers development of great significance.
