This organotin compound, known as dioctyltin dilaurate (DOTDL), is primarily used as a heat stabilizer in the production of polyvinyl chloride (PVC) materials. It enhances the thermal stability of PVC during processing, preventing degradation, discoloration, and loss of mechanical properties when exposed to heat. It is essential in manufacturing both rigid and flexible PVC products, such as pipes, profiles, cables, hoses, and flooring, ensuring long-term durability and performance. Additionally, it functions as a catalyst in the production of polyurethanes, particularly for flexible and rigid foams, and in the curing of silicone rubbers. It is also utilized in esterification and transesterification reactions, as well as in certain coatings and adhesives to improve stability and longevity.
