Lead Salt PVC Stabilizer
Introduction
Lead salt PVC stabilizers are divided into two categories: monomer and composite. They have excellent thermal stability, strong complexing ability, excellent electrical insulation, and low price.
Advantage
1. Excellent thermal stability, complex ability, can replace unstable chlorine atoms, high metal content, strong HCl absorption ability.
2. Excellent electrical insulation and low price.
3. Some varieties have good light resistance, and some have good lubricity. For example, the dibasic lead phosphite has good stability, has the functions of anti-oxidation and shielding ultraviolet rays, and can give the profile good light stability and outdoor thermal oxygen stability, and surface smoothness. Combined with TiO2 can reduce the amount of UV absorbers and antioxidants.4. Good processability, suitable for various processing techniques, and has a white pigment effect. The representative products of the monomer lead salt are ① tribasic lead sulfate ② dibasic lead phosphite ③ tribasic lead maleate ④ dibasic lead stearate ⑤ dibasic lead phthalate. The advantage of the monomer lead salt is its low cost. It is included in the formula with an independent ratio, and the adjustment of the formula system is more convenient.
