Thermal stabilizers PVC resin must be able to capture a self catalytic HCL released , or structural instability polyolefin resin can be produced from the addition of pvc reflection to prevent or reduce the decomposition of PVC resin. Usually the article in the formulation according to claim thermal stabilizer chosen species . Thermal stabilizers PVC resin must be able to capture a self catalytic HCL released , or structural instability polyolefin resin can be produced from the addition of pvc reflection to prevent or reduce the decomposition of PVC resin. Generally in the formulation according to the requirements of products to choose varieties such as heat stabilizers : lead salt stabilizer is mainly used in hard articles . Lead salt stabilizer has good heat stabilizers , excellent electrical properties , low cost and so on. However, its toxicity, easily contaminated products , can only produce opaque products. In recent years, large numbers of composite stabilizer , PVC foaming board stabilizer dangerous single component has been replaced . Features composite stabilizer is a dedicated and strong, little pollution , the advantages of simple ingredients and processing enterprises . But because no uniform standard , so the difference between the various composite stabilizer great . Barium cadmium -based stabilizers is a better performance heat stabilizers . PVC plastic sheeting used in wider . Usually barium cadmium and zinc and organic phosphite antioxidants and use .
