Lead methylmercaptide, a chemical compound derived from lead and methylmercaptan, is primarily recognized for its role as a heat stabilizer and antioxidant in the manufacturing of PVC (polyvinyl chloride) products. It functions as a metal deactivator, preventing the degradation of polymers by heat and light, thereby enhancing the durability and performance of PVC materials. However, its use is accompanied by significant concerns due to its toxicity to both humans and the environment, leading to environmental pollution and detrimental effects on the nervous system, kidneys, and reproductive organs. As a result, the application of lead methylmercaptide has been increasingly restricted, with a push towards the adoption of alternative stabilizers in PVC production.

Uses

Used in Plastics and Polymer Industry:
Lead methylmercaptide is used as a heat stabilizer for PVC products to prevent the degradation of the polymer caused by heat and light exposure. It serves as an antioxidant, enhancing the durability and performance of PVC materials by inhibiting the breakdown of the polymer chain.
Used in Chemical Stabilization:
As a metal deactivator, lead methylmercaptide is employed to mitigate the adverse effects of metal ions on the stability and quality of PVC products. It helps to maintain the integrity of the polymer and extend the lifespan of PVC-based items.
However, due to the recognized toxicity of lead methylmercaptide and its potential to cause environmental pollution and health hazards, there is a growing trend towards the development and use of safer, non-toxic alternatives in the stabilization of PVC materials. This shift aims to reduce the harmful impact on human health and the environment while still ensuring the production of high-quality PVC products.

Check Digit Verification of cas no

The CAS Registry Mumber 35029-96-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,0,2 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 35029-96:
(7*3)+(6*5)+(5*0)+(4*2)+(3*9)+(2*9)+(1*6)=110
110 % 10 = 0
So 35029-96-0 is a valid CAS Registry Number.
