Lead Based Compound Stabilizer For PVC Pipe Fitting

PVC pipes are prone to degradation at high temperatures, causing them to become brittle or deformed. Therefore, it is necessary to add stabilizers to improve their thermal stability. Lead based composite stabilizer is a commonly used stabilizer for PVC pipes, consisting of various components such as lead salts and organic acid salts. Lead salts can absorb HCl in the decomposition products of PVC, preventing it from further reacting with PVC molecules, thereby delaying the degradation process. Organic acid salts can neutralize the acidic substances generated during the decomposition process of PVC, preventing further damage to PVC molecules by acidic substances
