Baotou Rare-toxic PVC stabilizer successfully developed

After more than a year of trial and error , the Baotou Rare Earth Research Institute has successfully developed a non-toxic, environmentally friendly, and good long-term stability of the new rare earth PVC stabilizer. Currently in the test line is under construction , is expected to put into production that year .

At present , the domestic PVC production enterprises mainly use lead salt , stearic acid metal, organic tin stabilizers , among the most widely used lead salt stabilizer , but there are hazards such stabilizers environmental safety issues. Rare PVC stabilizer has a clear advantage in overall performance and cost , and environmental protection. The hospital engineer Zhang Xi introduced , accounting for 3.5% PVC stabilizer weight , and now the national production of 13 million tons per year PVC , and is still rising year by year , the imminent implementation of a comprehensive ban on the use of lead stabilizers on the urgent need of environmental protection , and efficient , cheap alternative. In addition, the main component of the rare earth lanthanum cerium stabilizer element content of about 10% , PVC terms of annual output 13 million tons per year to use 40,000 tons of elements lanthanum , cerium , which for digestion Baiyunebo lanthanum cerium element has surplus significance.
