For chemical manufacturers and formulators, the precise specifications of raw materials are non-negotiable. Dioctyl Phthalate (DOP) is no exception. As a foundational plasticizer, its performance in a wide range of applications, from PVC products to paints and dyes, hinges on its purity, physical properties, and adherence to established standards. As a dedicated supplier and manufacturer of Dioctyl Phthalate in China, we emphasize the importance of understanding these specifications to ensure optimal outcomes for our clients.

The chemical identity of Dioctyl Phthalate is definitively established by its CAS number: 117-84-0. This unique identifier is crucial for accurate product identification, regulatory compliance, and avoiding mix-ups in procurement. When you inquire about purchasing DOP, referencing this CAS number ensures that you are sourcing the correct compound for your specific needs.

Purity is arguably the most critical specification for any chemical raw material, and DOP is no different. High-purity Dioctyl Phthalate, typically specified as ≥99.5%, guarantees consistent performance, predictability in formulations, and minimizes the presence of impurities that could negatively affect the final product. Impurities can lead to variations in color, odor, viscosity, and ultimately, the physical properties of the plasticized material. As a responsible manufacturer, we maintain stringent quality control measures to ensure our DOP consistently meets or exceeds this purity benchmark.

Beyond purity, several physical and chemical properties are vital for manufacturers when evaluating DOP. These include:

• Appearance: Typically described as a colorless liquid, a clear and consistent appearance is an initial indicator of product quality.
• Acidity: Low acidity levels are desirable, as high acidity can indicate the presence of residual acidic impurities or degradation, potentially affecting material stability. Our specifications usually limit acidity to a very low percentage.
• Moisture Content: Minimal moisture content (e.g., ≤0.019%) is important to prevent issues during processing, such as hydrolysis or impacting the effectiveness of other components in a formulation.
• Density and Flash Point: These parameters are important for handling, storage, and safety considerations during the manufacturing process.

For industries that rely on Dioctyl Phthalate for applications like PVC processing, chemical fiber resins, paints, and dyes, understanding these specifications allows for informed purchasing decisions. When sourcing from China, it is imperative to partner with manufacturers who provide comprehensive documentation, including Technical Data Sheets (TDS) and Certificates of Analysis (CoA) for each batch. This transparency builds trust and ensures accountability.
