NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing insightful information on the chemical compounds we supply. Di(2-propylheptyl) phthalate (DPHP) is a sophisticated plasticizer with a specific chemical makeup that dictates its advantageous applications across several industries. Understanding these properties is key to leveraging DPHP for optimal product performance.

DPHP is a phthalate ester, chemically known as Di(2-propylheptyl) phthalate. Its molecular formula is C28H46O4. It is derived from the esterification of phthalic anhydride with isomeric C10 alcohols (2-propylheptanol). This specific C10 branched alkyl chain structure is fundamental to its unique performance characteristics, differentiating it from other plasticizers.

One of the most significant chemical properties of DPHP is its low volatility. This is a direct result of its higher molecular weight and the branched nature of its alkyl chains, which reduce its tendency to evaporate at elevated temperatures. This low volatility is critical for applications requiring high-temperature stability, such as in wire and cable insulation, where it prevents loss of plasticizer and maintains flexibility.

DPHP demonstrates excellent compatibility with Polyvinyl Chloride (PVC), a widely used polymer. It is miscible and compatible with all common monomeric plasticizers, allowing formulators flexibility in creating custom blends to achieve specific performance profiles. This compatibility ensures that DPHP integrates seamlessly into PVC formulations without phase separation, leading to uniform material properties.

The plasticizer's physical appearance is typically a clear, colorless to pale yellow liquid with a barely perceptible odor. This aesthetic quality is beneficial for applications where appearance is important, such as interior automotive components or consumer goods.

Beyond these properties, DPHP offers excellent heat aging performance and remarkable weathering resistance. Its molecular structure provides inherent stability against thermal degradation and UV radiation, making it suitable for outdoor applications like roofing membranes and tarpaulins. It also exhibits good resistance to extraction by water and other solvents.

The applications for DPHP are diverse, spanning:

  • Wire and Cables: For insulation and sheathing requiring flexibility and high-temperature resistance.
  • Automotive Interiors: For components needing low fogging, good anti-fogging properties, and UV stability.
  • Outdoor Applications: Such as roofing membranes and tarpaulins, where weather resistance is paramount.
  • Soft Plastics: General use in flexible PVC products for enhanced durability and performance.
