2.What is PVC calcium and zinc stabilizer?

PVC products used in the production of composite stabilizers are mostly used lead salt and metal soap compound stabilizer, due to its use of a large number of lead salt, resulting in environmental pollution, high plasticizing temperature, poor solution flow, the case of sulfur discoloration and other issues. Especially with the people of plastic products, environmental requirements are getting higher and higher, the development of non-toxic calcium and zinc composite stabilizer more and more people's attention. Non-toxic calcium and zinc compound stabilizer is calcium and zinc organic salts, phosphites, polyols, antioxidants and solvents and other components of the complex. Calcium and zinc stabilizer and resin and plasticizer compatibility, transparency is good, not easy to precipitate, the amount of less, easy to use.
