Dicapryl Phthalate (DCP), identified by CAS number 131-15-7, is a vital chemical compound widely employed as a plasticizer in various industrial sectors. Its efficacy stems from a unique combination of chemical structure and physical properties that impart enhanced performance to the materials it modifies. As a premier chemical manufacturer and supplier, we aim to provide comprehensive insights into this versatile product.

Chemically, Dicapryl Phthalate is an ester derived from phthalic acid and dicapryl alcohol. Its molecular formula, C24H38O4, and molecular weight of approximately 390.56 g/mol, contribute to its efficacy as a plasticizer. The branched alkyl chains of the dicapryl alcohol moiety are key to its superior performance characteristics, differentiating it from linear phthalates.

Physically, DCP is typically described as an oily, colorless to light yellow viscous liquid. It exhibits a relatively high boiling point and low volatility, which are crucial for applications involving elevated temperatures or requiring long-term stability. Its density is generally around 0.97-1.01 g/mL, and it shows good solubility in common organic solvents, though it is sparingly soluble in water. These properties make it amenable to various processing techniques.

The primary application of Dicapryl Phthalate is as a plasticizer for polymers, most notably Polyvinyl Chloride (PVC). Its key advantages include:

  • Enhanced Thermal Stability: DCP offers superior heat resistance compared to many other plasticizers, making it suitable for applications that experience high temperatures.
  • Excellent Light and Weather Resistance: It protects polymers from degradation caused by UV radiation and environmental exposure, leading to greater product longevity.
  • Good Viscosity Stability: Especially valuable in plastisol formulations, DCP ensures consistent processing viscosity, facilitating smooth manufacturing.
  • Versatility: It finds use in the production of cable materials, artificial leather, floor coverings, films, and other PVC-based products.

Many industries consider DCP as an effective alternative to Dioctyl Phthalate (DOP) due to its enhanced performance profile, particularly in demanding environments.
