Lead salt stabilizers has two categories:monomer and compound , in our country we use lead salt stabilizer as stabilizer basically, has excellent thermal stability, complexing capacity, excellent electrical insulation properties, low price and so on.
Excellent thermal stability, complexing capacity, labile chlorine atoms which may be substituted, a high metal content, strong absorption capacity of HCl.
2. Excellent electrical insulation, and low prices.
3. Some varieties of excellent light fastness, some breeds have a good lubricity. Such as dibasic lead phosphite, good stability, resistance to oxidation and ultraviolet shielding effect can be given profiles good light stability and outdoor thermal-oxidative stability, and surface finish. And TiO2 with UV absorbers and antioxidants can reduce the amount of PVC profiles Wo is the most widely applied in the amount of stabilizing system.
