For professionals in the chemical and plastics industries, understanding the specific properties of key raw materials is essential for optimal product development and manufacturing. Methyl Tin Mercaptide, identified by its CAS number 57583-35-4, is a highly regarded organotin compound widely utilized as a PVC heat stabilizer. This article provides an in-depth look at its chemical properties, benefits, and applications, highlighting why it's a preferred choice for manufacturers seeking high performance and safety. As a dedicated supplier of specialized chemicals, we aim to equip our clients with comprehensive knowledge.

Methyl Tin Mercaptide is characterized as a clear, transparent liquid with a molecular formula of C22H44O4S2Sn and a molecular weight of approximately 555.42. Its chemical structure, often a blend of methyltin and mercaptide components, is finely tuned to provide superior heat and light stabilization to Polyvinyl Chloride (PVC) formulations. Key physical and chemical properties include a specific gravity typically between 1.16-1.19 at 25℃ and a viscosity that ensures ease of handling and incorporation into PVC matrices. The tin content, generally around 19% or higher, is critical to its stabilizing function.

The primary functional advantage of Methyl Tin Mercaptide is its exceptional thermal stability. It effectively prevents the thermal degradation of PVC during processing, which is vital for applications involving high temperatures such as extrusion and injection molding. This leads to improved early color hold and long-term dynamic stability, ensuring that finished PVC products maintain their desired appearance and structural integrity. Furthermore, its excellent transparency makes it suitable for applications where clarity is a key requirement, such as in PVC films and sheets used for packaging and display purposes.

Safety is another significant attribute of Methyl Tin Mercaptide. Unlike some older or alternative stabilizers, it is recognized for its non-toxic nature and has been approved for use in sensitive applications. This includes food packaging materials and drinking water pipes, demonstrating its high safety profile and compliance with regulatory standards. This makes it a responsible choice for manufacturers committed to producing safe and environmentally sound products.

For businesses looking to purchase CAS 57583-35-4, understanding these properties is crucial for selecting the right grade and supplier. Our company ensures that the Methyl Tin Mercaptide we supply meets stringent quality controls, offering consistent purity and performance. We serve as a reliable supplier for companies seeking to enhance their PVC product lines with a stabilizer that delivers on stability, safety, and processing efficiency. By understanding the technical specifications of Methyl Tin Mercaptide, manufacturers can make informed decisions to optimize their formulations and achieve superior end-product characteristics.
