Ca-Zn stabilizer from the calcium, zinc, lubricants, antioxidants and the like as the main component and composite technology using a special synthetic. It can not only replace lead and cadmium salts and other toxic organic tin stabilizer, and has a very good thermal stability, light stability and transparency and tinting strength. Practice has proved that, in PVC resin products, good processing properties, heat stabilizers lead salt acts as a stabilizer, is a good non-toxic stabilizer. Product Features: There are PVC resin processing with good dispersion, compatibility, processing fluidity, adaptability, excellent surface smoothness; excellent thermal stability, the initial hue is small, no precipitation phenomena; free of heavy metals and other toxic ingredients without curing the phenomenon; Congo red test long time, has excellent electrical insulation, no impurities, with high weather resistance; wide range of applications, practical, with less versatility; white products, whiteness better than its similar products.
