High Quality Dibutyltin Dichloride with CAS number 683 - 18 - 1 is a well - known organotin compound. It is a colorless to pale yellow liquid under normal conditions. The molecular formula of Dibutyltin Dichloride is C₈H₁₈Cl₂Sn, and its molecular weight is approximately 303.84 g/mol. This product is known for its high purity, which ensures excellent performance in various applications. It has a boiling point around 220 - 225°C at a pressure of 10 mmHg and a density of about 1.38 g/cm³ at 25°C. It is soluble in common organic solvents such as benzene, toluene, and chloroform but insoluble in water.
High Quality Dibutyltin Dichloride has a wide range of applications. In the field of plastics, it is commonly used as a heat stabilizer. When added to polyvinyl chloride (PVC) products, it can effectively prevent the thermal degradation of PVC during the processing and long - term use, improving the heat resistance and durability of the products. This makes PVC products more suitable for high - temperature environments, such as in some industrial pipes, window profiles, and cable insulation materials.
It also serves as a catalyst in the production of polyurethane. In the reaction of isocyanates and polyols to form polyurethane, Dibutyltin Dichloride can accelerate the reaction rate, control the reaction process, and improve the quality and performance of the final polyurethane products. Polyurethane is widely used in foams, elastomers, coatings, and adhesives.
In the field of organic synthesis, it is used as a reagent for the synthesis of other organotin compounds. These derivatives have unique chemical properties and are used in many chemical reactions and industrial processes.
When using High Quality Dibutyltin Dichloride, it is necessary to follow strict safety and operating procedures. First, it should be stored in a cool, dry, and well - ventilated place, away from open flames and heat sources. During handling, appropriate personal protective equipment, such as chemical - resistant gloves, safety glasses, and a respirator, should be worn.
In the plastics industry, the recommended dosage of Dibutyltin Dichloride as a heat stabilizer is usually in the range of 0.1 - 3% (weight ratio), depending on the specific requirements of the PVC formulation and the processing conditions. It can be added directly to the PVC resin during the mixing process, and then the mixture is processed by extrusion, injection molding, or calendering to form the final products.
In the polyurethane production, the amount of Dibutyltin Dichloride used as a catalyst is generally very small, usually in the range of 0.01 - 0.1% (weight ratio). It should be added carefully during the reaction process to ensure uniform mixing and proper reaction control.
Case 1: PVC Pipe Production
A PVC pipe manufacturing company used High Quality Dibutyltin Dichloride as a heat stabilizer. They added 1.5% (weight ratio) of Dibutyltin Dichloride to their PVC resin. After the extrusion process, the produced pipes showed excellent heat resistance. During a high - temperature test at 80°C for 100 hours, the pipes maintained their mechanical properties, such as tensile strength and elongation at break, with only a small decrease compared to the initial values. This ensured the long - term reliability of the pipes in hot water supply systems.
Case 2: Polyurethane Foam Production
A furniture manufacturer produced flexible polyurethane foams for sofa cushions. They used 0.05% (weight ratio) of Dibutyltin Dichloride as a catalyst. With the addition of this catalyst, the reaction time of the polyurethane formation was significantly reduced. The produced foams had a more uniform cell structure, better elasticity, and higher comfort. The production efficiency was also improved, and the rejection rate of defective products was reduced.
