12141-20-7 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 12141-20-7 differently. You can refer to the following data:
1. solid
2. 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.
Flammability and Explosibility
Flammable
Check Digit Verification of cas no
The CAS Registry Mumber 12141-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,4 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12141-20:
(7*1)+(6*2)+(5*1)+(4*4)+(3*1)+(2*2)+(1*0)=47
47 % 10 = 7
So 12141-20-7 is a valid CAS Registry Number.
