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.
Basic Information；
Chinese name: Lead salt stabilizer
Classification: Monomers and composite
Advantages:
- Excellent thermal stability, complexing capacity, labile chlorine atoms which may be substituted, a high metal content, strong absorption capacity of HCl.
- Excellent electrical insulation, and low prices.
- 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.
- Good workability for a variety of processing technology, and has a white pigment effect. Representative monomers lead salt products are ① tribasic lead sulfate ② dibasic phosphate, tribasic lead maleate lead ③ ④ ⑤ dibasic lead stearate, dibasic lead phthalate. Advantage is the low cost of lead salt monomer, an independent ratio included in the recipe, recipe adjustment system more convenient.
Applications:
Mainly used in large wire and cable, and is also useful in rigid PVC products
