Calcium And Zinc Stabilizer

With the enhancement of environmental protection awareness in all countries in the world, environmental protection laws and regulations are gradually improved, especially the hygienic requirements for plastic products such as medicine, food processing, daily necessities, and toy plastics. Lead and cadmium salt stabilizers will eventually be fully replaced by non-toxic PVC stabilizers. . The production of foreign plastic additives will tend to be large-scale and specialized, environmental protection requirements are highly valued, and efficient and multi-functional. Research and development of new environmentally friendly and non-toxic PVC stabilizers has become an inevitable trend. The non-toxic direction of PVC heat stabilizers is mainly concentrated in two aspects of organotin and calcium-zinc composite heat stabilizers, and great progress has been made in both. It is mainly manifested in the successful research and extensive use of organotin heat stabilizers represented by the United States, and the popularization and application of non-toxic calcium-zinc composite heat stabilizers represented by Europe, but the price of organotin is too expensive. Calcium-zinc composite stabilizer will eventually build the future non-toxic PVC stabilizer system of all countries in the world
