For R&D scientists, product formulators, and procurement professionals in the chemical and materials industry, a deep understanding of chemical properties is fundamental to successful product development and sourcing. Cresyl Diphenyl Phosphate (CAS 26444-49-5) is a compound that warrants close examination due to its versatile application as both a plasticizer and a flame retardant. As a leading manufacturer and supplier, we aim to provide clear insights into the characteristics that make CDP a valuable industrial additive.

Chemically, Cresyl Diphenyl Phosphate is an organophosphate ester. Its molecular formula, C19H17O4P, indicates a complex structure that underpins its functional attributes. Typically supplied with a high purity of 99.5%, it presents as a colorless, transparent liquid. This visual clarity and purity are indicative of rigorous manufacturing processes, which are crucial for predictable performance in demanding applications.

The physical properties of CDP are equally important for its application. Its low freezing point (below -30°C) and relatively high boiling point (360°C at atmospheric pressure) suggest stability across a range of temperatures. The density of approximately 1.205-1.215 g/cm³ also plays a role in formulation calculations. These characteristics make it suitable for incorporation into various matrices without adversely affecting processing or stability.

From an application perspective, CDP’s compatibility with resins like PVC, nitrocellulose, and synthetic rubbers is a significant advantage. It not only enhances flame retardancy but also improves the flexibility and durability of these materials. This dual action is highly valued in sectors requiring robust performance, such as automotive parts, electrical insulation, and protective coatings. For companies looking to buy these performance-enhancing properties, sourcing CDP from a reliable supplier is essential.

Procurement managers and scientists often seek to understand the cost-effectiveness and availability of such chemicals. Engaging with a Chinese manufacturer for a price inquiry allows for direct access to market pricing and potential volume discounts. Ensuring a consistent supply chain and product quality is paramount when making purchasing decisions for critical intermediates like Cresyl Diphenyl Phosphate.
