PVC auxiliary stabilizer BS-QZD is a non-toxic new material with multi-hydroxyl base calcium magnesium aluminum salt as the main component, which is synthesized under specific conditions and then mixed and crushed. It has good complex characteristics with PVC unstable structure. In the processing of PVC mixture, it can absorb the unstable structures such as allyl chloride and HCl generated by heat well, and has a good complexation with zinc ions, effectively inhibiting the zinc burning phenomenon. Thus showing excellent thermal stability. This product has significant heat stability in soft and hard PVC products and foamed products, can replace Sek, hydrotalc, etc., for the processing of soft and hard PVC non-transparent products, and zinc stearate, calcium, hydrotalc, zeolite, β-dione, antioxidant and so on have a good synergism.
