Calcium and zinc stabilizers are synthesized by using a special composite process for calcium salts, zinc salts, lubricants, antioxidants, etc. as the main components. It can not only replace toxic stabilizers such as lead and cadmium salts and organotins, but also has fairly good thermal stability, light stability and transparency and coloring power. With PVC resin processing processing has good dispersion, compatibility, processing fluidity, wide adaptability, excellent surface finish of the product; Excellent thermal stability, small initial hue, no precipitation; No heavy metals and other toxic components, no vulcanization phenomenon; Congo red test time is long, with excellent electrical insulation, no impurities, with high efficiency weather resistance; Wide range of application, strong practicality, small dosage, multi-functionality; Among white products, the whiteness is better than that of similar products.
