Processing Aid
Tribasic lead sulfate
Appearance: White powder without evident mechanical impurity
Lead oxide content: 89.0-+1.0 %
Sulfur trioxide: 7.8-8.5 %
Heating loss: 0.3% max
Fineness: (mesh of 0.075mm) 99.7% min
Packing: 25kg/bag
Molecular formula: 3PbO. PbSO4. H2O
Molecular weight: 990.86
Property: It is white, sweet and toxic powder with specific gravity of 7.10. It can dissolve in nitric acid, hot thick hydrochloric acid, ammonium acetate and sodium acetate partly in acetic acid, but not in water. It will become yellow when loses the crystal water at 135 degree. It become yellow under sunlight, specially in wet condition.

Application: Mainly used for the hot stabilizer of PVC opaque or semiopaque plastic products.
Storage and Transportation: It can be kept in a dry and cool storehouse with good ventilation and cannot be stored or transported with food because being toxic inorganic products.
Dibasic lead phosphite
Appearance: White powder without evident mechanical impurity
Lead oxide content: 90.0-+1.0 %
Phosphorous acid: 11.0 -+1.0%
Moisture: 0.3% max
Fineness (mesh of 0.075mm): 99.7% min
Packing: 25kg/bag
Molecular formula: 2PbO. PbSO3.1/2H2O
Molecular weight: 742.57
Property: It is white, sweet and toxic powder with specific gravity of 6.94. It can dissolve in nitric acid and hydrochloric acid, but not in water. It will become grey or black at about 200 degree to yellow at 450 degree, but in a good reductibility. As an antioxidant, it has excellent performance of resistance to ultraviolet ray, cold and ageing.
Application: Mainly used as stabilizer of PVC opaque products because of good insulation, weather ability and ultraviolet radiation absorbency.
Storage and Transportation: It can be kept in a dry storehouse with good ventilation and separate with humidity, sour gas and sulfureted hydrogen gas in order not to go bad. It cannot be transported with food and much attention will be paid to it because it is flammable and toxic.
