Heat stabilizer is one of the important categories in the plastics additives, heat stabilizer of synchronization with the birth and development of PVC resin, mainly used for PVC resin processing, so the heat stabilizer and the proportion of PVC resin, PVC soft products has a close relationship.

          The key development of lead-free thermal stabilizer is rare earth thermal stabilizer, organic tin thermal stabilizer and calc-zinc compound heat stabilizer. Enterprises in our country in the world to realize the industrialization of rare earth heat stabilizer, raw materials of rare earth elements mainly lanthanum, cerium rare earth compound products, safety and health, no radiation, over the years the production of plastic toys, for export in the international market enjoys a reputation. China has the advantage of rare earth resources, and the rare earth thermal stabilizer should be the preferred direction of China's development of lead-free thermal stabilizer.

               Composite heat stabilizer can be integrated a variety of characteristics of heat stabilizers, including calcium, zinc composite heat stabilizer nonpoisonous and harmless, is mainly used for food packaging plastic products, plastic products, such as thermal stability but not ideal, to promote the broader, needs to be used with other heat stabilizers. Organic tin thermal stabilizer is the leading variety of European and American countries. The comprehensive performance is good, but the price is high, and there is a lot of room for development in China in the future.

           China's plastic additives need to be constantly innovated and upgraded to meet the development of The Times.
