In the realm of industrial chemicals, Dioctyl Adipate (DOA), known by its CAS number 123-79-5, is a fundamental compound valued for its exceptional plasticizing properties. This diester plays a critical role in modifying the physical characteristics of polymers, particularly PVC, enhancing their flexibility, durability, and processability. For businesses seeking to improve their product performance, understanding DOA's properties and reliable sourcing channels is key.

Dioctyl Adipate is characterized by its clear, colorless oily liquid appearance. Its chemical structure, C22H42O4, with a molecular weight of 370.57, dictates its low volatility and excellent compatibility with a wide range of polymers. Key physical properties include a density of approximately 0.925 g/cm³, a boiling point above 148.9°C, and a refractive index of around 1.447. These attributes make it highly suitable for applications requiring good performance at both ambient and low temperatures.

The primary industrial application of Dioctyl Adipate is as a plasticizer in PVC. It is extensively used in the manufacturing of flexible PVC products such as electrical wire insulation, automotive components, flooring materials, films, and hoses. Its ability to impart excellent low-temperature flexibility and resistance to extraction by soapy water further broadens its utility. Beyond PVC, DOA can also be found in applications involving synthetic rubbers, nitrocellulose, and ethyl cellulose, acting as a softener and modifier.

For companies looking to purchase Dioctyl Adipate, China offers a robust market with numerous manufacturers and suppliers. When searching for a reliable source, it is advisable to look for suppliers who can consistently deliver high-purity product (typically ≥99%) and provide comprehensive technical data sheets and safety data sheets (SDS). Understanding pricing structures, minimum order quantities, and delivery capabilities is also crucial for effective procurement. Many Chinese suppliers are well-equipped to handle both small and large-scale orders, catering to diverse client needs.

When seeking to buy DOA, consider the specific grade and certifications required for your application. Reputable manufacturers often adhere to international quality standards, such as ISO certifications, ensuring product reliability. Engaging directly with suppliers allows for direct price inquiries and potential negotiation for bulk purchases, leading to cost efficiencies. The availability of product samples for testing can also be a valuable step in ensuring the material meets your precise formulation requirements.

In summary, Dioctyl Adipate (CAS 123-79-5) is a vital chemical for enhancing polymer flexibility and performance. By understanding its properties and collaborating with trusted Chinese manufacturers and suppliers, businesses can ensure a consistent and cost-effective supply of this essential industrial ingredient.
