| LEAD PHOSPHITE, DIBASIC Usage And Synthesis |
| Chemical Properties | solid |
| Chemical Properties | Dibasic lead phosphite is a white crystalline powder, sp gr 6.9, refractive index 2.25, lead oxide content 90.2%, sieve analysis, 99.8% through 44 μm (325 mesh) (wet), water solubility, nil. |
| Uses | Fields of application for dibasic lead phosphite stabilizers in PVC include garden hose, flexible and rigid vinyl foams (as high temperature activator for azodicarbonamide-type blowing agents), coated fabrics, plastisols, electrical insulation, and extruded profiles for outdoor use. In general, at five parts per hundred of resin (5 phr), dibasic lead phosphite provides good heat stability and superior outdoor weathering properties in PVC. This stabilizer should be stored in closed containers, away from open flames, and at temperatures below 200 °C. Exposure to sparks or static electricity should be avoided by grounding all electrical equipment and using wooden scoops. |
