Product Name:Dibasic Lead Phosphite
English Name:Dibasic Lead Phosphite
CAS No.:12141-20-7
Aliases:Lead phosphite, dibasic, Dibasic lead phosphite hemihydrate
Molecular Formula:2PbO·PbHPO3·1/2H2O
Physical Properties:White to slightly yellow crystalline powder with relative density of about 6.0. Stable in air, insoluble in water, ethanol and acetone, soluble in nitric acid, hydrochloric acid and acetic acid. Decomposes at about 300°C, with excellent heat and light stability.
Uses:Used as a heat stabilizer for PVC (polyvinyl chloride), especially suitable for opaque, outdoor weathering and wire and cable products. It provides excellent thermal and light stability and imparts good aging resistance to the products.
Technical Specifications:
Appearance: white or slightly yellow powder
Lead oxide content (as PbO): 88.0%~91.0%
Phosphorous acid content (as H3PO3): 9.0%~11.0%
Moisture content (105°C×2h): ≤0.5%
Fineness (through 100 mesh): ≥99.5%
