Factory Supply Dibutyltin Diacetate, with the CAS number 1067 - 33 - 0, is a chemical compound that has gained popularity in various industrial applications. The chemical formula of Dibutyltin Diacetate is C₁₂H₂₄O₄Sn. It appears as a clear to pale - yellow liquid at room temperature. This product is typically offered at a low price, which makes it an attractive option for large - scale industrial use.
It has a molecular weight of approximately 351.02 g/mol. The boiling point of Dibutyltin Diacetate is around 135°C at 0.5 mmHg, and its density is about 1.32 g/cm³. It is soluble in common organic solvents such as benzene, toluene, and chloroform, but insoluble in water.
Dibutyltin Diacetate is widely used as a catalyst in the production of polyurethane foams. In this process, it helps to accelerate the reaction between polyols and isocyanates, leading to the formation of a stable foam structure. It can also be used in the production of silicone rubber, where it acts as a cross - linking catalyst, improving the mechanical properties and heat resistance of the rubber.
Another important application is in the production of PVC stabilizers. Dibutyltin Diacetate can prevent the degradation of PVC under high - temperature processing conditions, thus extending the service life of PVC products. Additionally, it is used in the production of coatings and adhesives, where it enhances the curing process and improves the adhesion properties.
When using Dibutyltin Diacetate, it is important to follow safety procedures. First, ensure that you are working in a well - ventilated area to avoid inhalation of the vapor. Wear appropriate personal protective equipment, such as gloves and safety glasses.
In the polyurethane foam production, the amount of Dibutyltin Diacetate added depends on the specific formulation and the desired properties of the foam. Usually, it is added in the range of 0.1% - 1% by weight of the polyol component. For silicone rubber production, the catalyst is usually added during the mixing process, and the dosage is carefully adjusted according to the reaction speed and the final properties of the rubber.
In PVC stabilizer production, the addition of Dibutyltin Diacetate should be carried out under controlled temperature conditions. It is typically added during the compounding process of PVC resin with other additives.
Case 1: A polyurethane foam manufacturing company was facing issues with slow curing speed and inconsistent foam quality. After switching to using Factory Supply Dibutyltin Diacetate as the catalyst, they noticed a significant improvement in the curing time. The foam production cycle was shortened by 30%, and the foam density became more uniform. This led to a 20% increase in production efficiency and a reduction in product rejection rate.
Case 2: A silicone rubber manufacturer was looking for a way to improve the heat resistance of their products. By adding an appropriate amount of Dibutyltin Diacetate as a cross - linking catalyst, the heat resistance of the silicone rubber was enhanced. The rubber could now withstand temperatures up to 200°C for a longer period without significant degradation, which opened up new market opportunities for high - temperature applications.
Case 3: A PVC pipe production plant was experiencing problems with PVC degradation during the extrusion process. After incorporating Dibutyltin Diacetate into their PVC stabilizer formulation, the pipes showed better color stability and longer service life. The rate of pipe failure due to thermal degradation was reduced by 40%, resulting in cost savings and improved customer satisfaction.
