Insufficient stability in the production process of pvc sheet
May 09, 2022
PVC calcium zinc stabilizer plays a considerable role in the production process of PVC sheet, which determines whether the sheet can be produced smoothly. A good stabilizer must contain high-quality hydrotalcite in it, which can prolong the stability time. In 183 minutes, the initial whiteness is greatly improved by 28%. The product characteristics of hydrotalcite FM300 are particularly suitable for the production of calcium-zinc stabilizers for PVC sheets. Its product characteristics mainly include
-High stability: the unique acid absorption mechanism causes its thermal stability to be higher than that of lead-based;
-High transparency: the same mechanism as PVC;
-High insulation: through the exchange reaction with anion, the absorbed chloride will not be released, and the insulation is excellent;
-High safety: After testing, hydrotalcite can be used in food packaging bags made of polymer materials;
-Good weather resistance: strong environmental adaptability;
-Will not produce vulcanization pollution: can be used in conjunction with various heat stabilizers.
