Product Overview
These Dibasic Lead Phosphite DBLP 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 200a , it turns to yellow at 450a , and it has good deductibility. It is antioxidant; it has the excellent performance of resistance to ultraviolet ray, cold, and ageing. Molecular formula: 2PbO a c PbHPO3 a c H2O Molecular weight: 742.57 Application: Mainly used for the heat 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.
