For chemical formulators and product developers, a deep understanding of the properties of raw materials is fundamental to creating effective and high-performing products. Dioctyl Phthalate (DOP) is a prominent plasticizer that enhances material flexibility and durability, making it a sought-after ingredient across various industries. Whether you are working with PVC, paints, coatings, or adhesives, grasping the key physical and chemical characteristics of DOP is essential for optimal application. As a leading supplier, we provide high-quality DOP and aim to equip our B2B clients with the knowledge they need to excel.

One of the first aspects formulators consider is the molecular structure and weight. Dioctyl Phthalate has the molecular formula C₂₄H₃₈O₄, with a molecular weight of approximately 390.56 g/mol. This relatively high molecular weight contributes to its low volatility, a crucial characteristic that ensures it remains within the polymer matrix even at elevated temperatures or during extended use. When manufacturers look to buy DOP, this low volatility means reduced loss of plasticizer over time, leading to sustained flexibility and material integrity. This is a key factor for product longevity, particularly in demanding industrial environments.

The physical state and appearance of a chemical are also vital for handling and formulation. Dioctyl Phthalate is typically described as a colorless to light yellow, oily liquid. It possesses a mild, characteristic scent. Its density is approximately 0.98–0.99 g/cm³ at 20°C. This density is important as it influences how well DOP mixes with polymers and other additives in a formulation. Its liquid state at room temperature simplifies handling and blending processes, making it easier for manufacturers to incorporate into their production lines. When you purchase DOP, consistency in these physical properties from your supplier is key.

Another critical property is the boiling point. Dioctyl Phthalate boasts a high boiling point, around 384°C (723°F). This high boiling point is directly linked to its low volatility and thermal stability. It means that DOP can withstand higher processing temperatures without significant evaporation or degradation, which is advantageous during compounding and manufacturing processes. For formulators working with high-temperature extrusion or molding techniques, this thermal stability is a significant benefit. Securing DOP with such properties from a reputable China supplier ensures your processes run smoothly.

In summary, understanding the molecular weight, appearance, density, and boiling point of Dioctyl Phthalate provides valuable insights for chemical formulators. These properties collectively contribute to DOP's effectiveness as a plasticizer, enhancing material flexibility, durability, and processability. If your company needs to buy high-quality DOP for your industrial applications, partnering with a knowledgeable and reliable manufacturer is crucial.
