PVC in the process of processing due to the role of shear force will remove hydrogen chloride to form free and peroxy free radicals and cause degradation, and its degradation shows the corresponding characteristic color. In order to effectively inhibit the degradation of product color and mechanical properties caused by this degradation, the heat stabilizer has become an indispensable main auxiliary agent for PVC processing, in the PVC processing process it can reduce or delay the generation of hydrogen chloride by replacing unstable chlorine atoms, neutralizing hydrogen chloride and eliminating or inhibiting free radicals in the process. With the rapid development of the PVC industry, the market demand for heat stabilizers has also increased significantly.

However, due to the level of economic development and other reasons, Many countries have long mainly used lead salt heat stabilizer, according to statistics, so far in PVC heat stabilizer accounted for about two-thirds, while non-toxic heat stabilizer less than 15%. Lead salt heat stabilizer has always been the main variety of PVC heat stabilizer because of its excellent thermal stability and low price. However, research has found that lead salt, as a harmful metal compound, is easy to be extracted from PVC products by water and bath agents, thus entering the human body through various ways to cause harm. Lead is a typical multi-affinity pendant, which has accumulation in the body, can form basophobic lead in the blood, and exists in the skeleton in a stable form, and has toxic effects on various tissues. Therefore, in recent years, a series of relevant policies have been introduced to restrict the use of heavy metals such as lead.

As one of the many calcium and zinc stabilizer manufacturers in China, Homart Technology has a strong production capacity and advanced production technology, can produce a variety of specifications of calcium and zinc stabilizer. Ca-Zn Stabilizer designed by Homart technical team not only include calcium salt, zinc salt, antioxidant but also added coupling agent. So, it is have excellent initial coloring performance, good lubricity and weather resistance which can improve the outdoor use effect of the product, Its coupling agent can promote the mixing materials uniform plasticization and improve the smooth surface and reduce production cost.

It is believed that with the development of times and technology, calcium and zinc stabilizers will be more and more widely used
