At present, PVC heat stabilizers mainly include lead salts, composite calcium and zinc, organic tin, organic antimony, organic auxiliary heat stabilizers and rare earth compounds. The largest output is the traditional lead salt stabilizer and Ca Zn composite stabilizer.
Ca Zn stabilizer is green and environmentally friendly without heavy metal elements, such as lead and separator.It can meet the requirements of the latest environmental protection standards in various countries.
Ca Zn stabilizer is resistant to vulcanization pollution. Ca Zn stabilizer has good system switching characteristics.When the traditional composite lead thermal stabilizer is converted to an organotin thermal stabilizer, cross-contamination will occur, resulting in high system switching costs, while the Ca Zn thermal stabilizer does not react with these two thermal stabilizers, and the switching cost is low.
The density of Ca Zn stabilizers is low, and the amount of calcium carbonate can be increased appropriately to reduce costs. Compared with the composite lead heat stabilizer, the density of the Ca Zn heat stabilizer is about 40%.
Aimsea is a national high-tech enterprise specializing in the integration of research, production and sales of non-toxic environmentally friendly PVC stabilizers.
The stabilizers are used widely in PVC products, such as wire and cable, toy medical equipment , transparent products, calendered products, pipe fittings, decorative sheets, foamed shoes, door and window profiles, etc.
