Heat stabilizer is one of the important categories in plastic auxiliaries. The heat stabilizer is synchronized with the birth and development of PVC resin. It is mainly used in the processing of PVC resin. Therefore, the ratio of heat stabilizer to PVC resin and PVC is very close relationship.

Lead-free heat stabilizer is the focus of the development of rare earth heat stabilizer, organic tin heat stabilizer and calcium – zinc complex heat stabilizer. China’s enterprises in the world’s first to achieve the industrialization of rare earth heat stabilizer, raw materials, rare earth elements are lanthanum, cerium rare earth compounds, safe and hygienic, non-radioactive, over the years for the export of plastic toys production, in the international market enjoyed considerable popularity. China has the advantage of rare earth resources, rare earth heat stabilizer should be used as China’s development of lead-free heat stabilizer preferred direction.

Composite heat stabilizer can be integrated with a variety of heat stabilizer characteristics, including calcium – zinc composite heat stabilizer non – toxic harmless, mainly used for food packaging with plastic products, plastic film products, but the thermal stability is not ideal, to In a wider range of promotion, need to be used in conjunction with other heat stabilizers. Organic tin heat stabilizer is the leading species in Europe and the United States, comprehensive performance is good, but the price is higher, China has a greater room for future development.

China’s plastic additives need to continue to innovate and develop, upgrading in order to meet the development of the times.
