High Quality Dioctyl Sebacate with the CAS number 122 - 62 - 3 is a widely - used chemical product. Its molecular formula is C26H50O4, and the molecular weight is approximately 426.67 g/mol. This product is a colorless to pale yellow clear oily liquid at room temperature. It has a mild odor and a relatively low volatility.
With a boiling point of around 377°C, Dioctyl Sebacate has good thermal stability. The density is about 0.91 g/cm³ at 20°C. It is insoluble in water but soluble in most organic solvents such as ethanol, acetone, and toluene. This high - quality product is produced under strict quality control standards, ensuring a high purity level and low impurity content, which makes it suitable for a variety of applications.
Dioctyl Sebacate has a wide range of applications. In the plastics industry, it is commonly used as a plasticizer. It can improve the flexibility, toughness, and cold - resistance of plastics. For example, when added to PVC (polyvinyl chloride) products, it can make the PVC more flexible and easier to process, and also enhance its performance in low - temperature environments.
In the rubber industry, it can be used as a softener. It helps to reduce the viscosity of rubber compounds during processing, improves the dispersion of fillers, and enhances the physical properties of the final rubber products, such as tensile strength and elongation at break.
It is also used in the production of lubricants. Dioctyl Sebacate can improve the lubricity and anti - wear properties of lubricants, and is particularly suitable for high - performance lubricants used in automotive and industrial machinery.
When using Dioctyl Sebacate as a plasticizer in plastics production, the recommended addition amount usually ranges from 5% to 15% depending on the specific plastic resin and the desired properties of the final product. First, the plastic resin and other additives are mixed according to the formula. Then, Dioctyl Sebacate is added gradually under stirring. The mixture is then heated and processed through extrusion, injection molding, or other forming processes.
As a softener in rubber processing, it is added during the mixing stage of the rubber compound. The amount is typically 2% - 10% of the total rubber compound. After adding, the mixture is kneaded thoroughly in a mixer to ensure uniform dispersion. The rubber compound can then be further processed into various rubber products.
When used in lubricants, Dioctyl Sebacate is blended with base oils and other additives. The concentration can vary from 5% to 20% depending on the performance requirements of the lubricant. The blending process usually involves heating and stirring to ensure a homogeneous mixture.
Case 1: A PVC pipe manufacturing company was facing problems with the brittleness of their pipes, especially in cold - weather regions. They decided to use Dioctyl Sebacate as a plasticizer. By adding 8% of Dioctyl Sebacate to their PVC resin, they noticed a significant improvement in the flexibility and impact resistance of the pipes. The pipes became more durable and less prone to cracking in low - temperature environments, which greatly enhanced customer satisfaction and increased the company's market share in cold - climate areas.
Case 2: A rubber seal manufacturer was struggling with the high viscosity of their rubber compounds during processing, which led to uneven product quality and low production efficiency. After adding 5% of Dioctyl Sebacate as a softener, the viscosity of the rubber compounds decreased, and the fillers were more evenly dispersed. As a result, the production process became smoother, and the quality of the rubber seals improved, with better sealing performance and longer service life.
Case 3: An automotive lubricant producer wanted to develop a high - performance lubricant for engines. By incorporating 12% of Dioctyl Sebacate into their base oil and other additive package, they achieved a lubricant with excellent anti - wear and lubricity properties. The lubricant reduced engine friction and wear, improved fuel efficiency, and extended the engine's service life, which was well - received by automotive manufacturers and consumers.
