12141-20-7 Usage
Description
LEAD PHOSPHITE, DIBASIC is a white crystalline powder with a specific gravity of 6.9, refractive index of 2.25, and lead oxide content of 90.2%. It has a sieve analysis of 99.8% through 44 μm (325 mesh) (wet) and is insoluble in water. It is used as a stabilizer in PVC applications.
Uses
Used in Plastics and Polymer Industry:
LEAD PHOSPHITE, DIBASIC is used as a stabilizer for polyvinyl chloride (PVC) to provide good heat stability and superior outdoor weathering properties. It is commonly used in garden hoses, flexible and rigid vinyl foams, coated fabrics, plastisols, electrical insulation, and extruded profiles for outdoor use.
Used in High Temperature Activator:
In the production of PVC foams, LEAD PHOSPHITE, DIBASIC is used as a high-temperature activator for azodicarbonamide-type blowing agents.
Storage and Safety:
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.
