What is PVC calcium zinc stabilizer?

The composite stabilizers used in the production of PVC products mostly use lead salts and metal soap composite stabilizers. Due to the large use of lead salts in their formulas, it causes problems such as high environmental pollution, high plasticization temperature, poor solution fluidity, and discoloration when encountering sulfur. Especially with the increasing environmental requirements for plastic products, the development of non-toxic calcium zinc composite stabilizers has attracted increasing attention. Non toxic calcium zinc composite stabilizer is a composite of calcium zinc organic salts, phosphites, polyols, antioxidants, and solvents. Calcium zinc stabilizer has good compatibility with resins and plasticizers, good transparency, is not easy to precipitate, and has a small dosage, making it easy to use.
