## Physical Properties: Boiling PointBoiling Point
The boiling point of dioctyl phthalate is approximately 384degC (723degF).The boiling point for dioctylphthalate is around 384degC (723degF). This relatively high boiling point is a significant characteristic.This relatively high boiling temperature is a very important characteristic. It means that DOP remains in a liquid state over a wide range of temperatures that are commonly encountered in industrial processes and in the end - use products.DOP is liquid at a wide range temperatures, including those found in industrial processes and end-use products. In the production of polyvinyl chloride (PVC) products, such as pipes, cables, and flooring, DOP is added to PVC resins.In the production process of polyvinyl-chloride (PVC), such as pipes and cables, or flooring, DOP resins are added. During the manufacturing process, which often involves heating and shaping the PVC - DOP mixture, the high boiling point of DOP ensures that it does not evaporate easily.The high boiling point ensures that DOP does not evaporate during the manufacturing process. This involves heating and molding the PVC-DOP mixture. This stability in the liquid phase allows it to effectively plasticize the PVC, making the material more flexible and workable.This stability in liquid phase allows DOP to plasticize PVC effectively, making it more flexible and workable. If DOP had a lower boiling point, it could vaporize during processing, leading to inconsistent product quality and potential loss of the plasticizing effect.DOP with a lower boiling temperature could vaporize, resulting in inconsistent product quality, and possibly losing its plasticizing effect.

## Physical Properties: Density## Physical Properties : Density
The density of DOP is around 0.986 g/cm3 at 20degC.The density of DOP at 20degC is approximately 0.986g/cm3. Density is an important physical property as it affects how DOP interacts with other substances in a mixture.The density of DOP is an important property because it influences how DOP reacts with other substances when mixed. In the formulation of plastics, the density of DOP influences the overall density of the plastic product.In the formulation of plastics the density of DOP affects the overall density. For instance, in the production of PVC films, the addition of DOP with its specific density will change the density of the final film.In the production of PVC film, for example, adding DOP will change the final density. This can be crucial for applications where the weight - to - volume ratio of the product is important, such as in packaging materials.This is especially important for applications that require a high weight-to-volume ratio, such as packaging materials. A lower - density plastic film made with DOP may be more desirable in some packaging applications as it can reduce the overall weight of the package, leading to cost savings in transportation.In some packaging applications, a lower-density plastic film made from DOP can be more desirable as it can reduce overall weight and cost savings during transportation. Additionally, the density of DOP also plays a role in its storage and handling.The density of DOP is also important for its storage and handling. Knowing the density helps in accurately measuring and dispensing the appropriate amount of DOP during the manufacturing process.Knowing the density allows you to accurately measure and dispense the correct amount of DOP in the manufacturing process.
