Some common sense and application of calcium zinc stabilizer

   It is reported that the current wide application of calcium zinc stabilizer is still in the plastic industry,which is used in the production process of plastic parts,plastic pipes,plastic films,wires and cables.The market trend of these products is largely dependent on the development of the construction industry.Therefore,the rise and fall of the construction industry plays a crucial role in the market demand for calcium and zinc stabilizers.
  Due to the different metal activities,various metal soaps formed in the composite calcium zinc stabilizer system have different stabilizing abilities on PVC.In addition to Ca/Zn composite calcium zinc stabilizer,there are also Ca/Zn/Sn,Al/Ca/Zn,Ca/Zn/Mg,Re/Zn composite new calcium zinc stabilizer.If zinc or tin soap with high activity is combined with barium,cadmium,zinc and other soaps,the synergistic effect can be produced and good stability can be obtained.
  Calcium-zinc stabilizer system is developed and applied both inside and outside the industry.Calcium-zinc compound hot calcium-zinc stabilizer is one of the promising varieties.The commonly used calcium and zinc hot calcium and zinc stabilizer is cheap and has good lubricity.Moreover,it is very similar to the formula system of lead salt in terms of formula,lubrication mechanism and processing technology,so it is easy to replace and convert lead salt,but its heat stability is poor,and zinc soap often causes"zinc burning"of products.The use of zinc soap is also limited in the occasions where the product performance is higher.Ca/Zn composite calcium zinc stabilizer is divided into solid and liquid.In the process of PVC product processing,the chloride generated by the reaction of HCl released by PVC and zinc compound is the catalyst for the degradation of PVC polymeric materials.The role of calcium carboxylate is that once the above zinc polymeric complex is formed,it can neutralize HCl and convert the zinc polymeric complex into zinc chloride.So that the polymer stability,is a kind of PVC processing hot calcium zinc stabilizer.
