Product description

Lead salt stabilizers are divided into two categories: monomer and composite. In my country, lead salt stabilizers are basically used as the main stabilizer. They have excellent thermal stability, strong complexing ability, excellent electrical insulation, and low price.

Advantage

1. Excellent thermal stability, complexing ability, can replace unstable chlorine atoms, high metal content, and strong HCl absorption ability.

2. Excellent electrical insulation and low price.

3. Some varieties have excellent light fastness, and some varieties have good lubricity. For example, the dibasic lead phosphite has good stability, has the functions of anti-oxidation and UV shielding, and can give the profile good light stability and outdoor thermal oxygen stability, and surface smoothness. Combined use with TiO2 can reduce the amount of ultraviolet absorbers and antioxidants. Hechuan is the most widely used stable system in PVC profiles in my country.

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.
