Dibasic Lead Phosphite

Molecular formula: 2PbO · PbHPO3 · H2O

Molecular weight: 742.57

Property:

It is slight white, sweet and toxic powder with the specific gravity of 6.94. It can dissolve in hydrochloric acid, and nitric acid, but not in water. It will turns to gray & black at 200°C, it turns to yellow at 450°C, and it has good deductibility. It is antioxidant; it has the excellent performance of resistance to ultraviolet ray, cold, and ageing.

 

Application:

Mainly used as the stabilizer of PVC opaque products because of good insulation, weatherablity and ultraviolet radiation absorbency.

 

Package: Plastic weaved bag, lined with PE bag, and 25Kg weight.

Storage:

It is toxic inorganic product, so it should be kept in a dry and cool storage house with good ventilation, and cannot be stored or transported with food.
