Ningbo Inno Pharmchem Co., Ltd. focuses on providing insights into essential industrial chemicals, and Dioctyltin Dilaurate (DOTL), with CAS number 3648-18-8, is a prime example. Understanding its detailed cas 3648-18-8 chemical properties is fundamental to appreciating its wide-ranging applications as a stabilizer and catalyst in sectors from PVC production to advanced polymer synthesis.

Dioctyltin Dilaurate is characterized by its chemical formula C₄₀H₈₀O₄Sn and a molecular weight of approximately 743.77 g/mol. It typically presents as a colorless to pale yellow, viscous liquid at room temperature. Key physical properties include a melting point between 17-18°C and a density of around 0.998 g/cm³. Crucially, DOTL is insoluble in water but readily dissolves in many organic solvents like methanol and acetone, which facilitates its incorporation into various formulations. Its stability under typical processing conditions further enhances its utility.

The primary industrial applications for DOTL stem from these properties. As a heat stabilizer for PVC, it prevents the degradation of polyvinyl chloride under heat, a process critical for manufacturing durable PVC products like pipes, cables, and packaging materials. Its effectiveness in this role, coupled with a comparatively lower toxicity profile than some other organotins, makes it suitable for sensitive applications. When you buy Dioctyltin Dilaurate for PVC applications, you are investing in product longevity and safety.

Furthermore, DOTL functions as an important polyurethane catalyst. It accelerates the reaction between isocyanates and polyols, essential for forming polyurethane foams, coatings, adhesives, and sealants. This catalytic activity allows manufacturers to control reaction kinetics and achieve desired material properties, thereby optimizing production efficiency and product quality. Similarly, it acts as a silicone catalyst, crucial for the curing of silicone elastomers and sealants, improving their mechanical strength and thermal resistance.

The compound's role in other industrial processes, such as in certain coatings and inks, further demonstrates its versatility. The ability to procure high-quality DOTL from a reliable supplier is essential for achieving consistent results. Ningbo Inno Pharmchem Co., Ltd. ensures that the DOTL provided meets the stringent purity and performance standards required by these advanced manufacturing processes.

In summary, Dioctyltin Dilaurate is a multifaceted chemical compound whose specific properties make it invaluable for industrial applications. Its effectiveness as a PVC heat stabilizer, polyurethane catalyst, and silicone catalyst cements its position as a key chemical in modern manufacturing. By understanding its attributes, industries can better leverage DOTL for innovation and enhanced product performance.
