In the realm of chemical manufacturing and product formulation, Dioctyl Phthalate (DOP) stands out as a cornerstone plasticizer, particularly for Polyvinyl Chloride (PVC) products. For procurement professionals and product developers, understanding the detailed properties and applications of DOP is vital for making informed purchasing decisions. This guide aims to provide a comprehensive overview, emphasizing how to best source this critical material.

What is Dioctyl Phthalate (DOP)?

Dioctyl Phthalate, commonly known as DOP, is an organic ester compound with the chemical formula C24H38O4 and CAS number 117-81-7. It is a colorless, viscous liquid characterized by its low volatility, good thermal stability, and excellent compatibility with a wide range of polymers. Its efficiency in imparting flexibility and improving the mechanical properties of plastics has cemented its status as a leading general-purpose plasticizer.

Key Properties of DOP:

  • High Purity: Typically available with a purity of 99.5% or higher, ensuring consistent performance.
  • Excellent Thermal Stability: Maintains integrity at elevated temperatures, crucial for processing.
  • Good Pigment Absorption: Facilitates vibrant and stable coloration in plastic products.
  • Low Volatility: Minimizes material loss during processing and in the final product.
  • UV Resistance: Offers some protection against degradation from ultraviolet light.
  • Compatibility: Works well with PVC, synthetic rubber, and various other resins.

Where to Buy DOP: Applications and Market Insights

The demand for DOP is driven by its extensive use across multiple industries. If you are considering to buy Dioctyl Phthalate, you’ll find it indispensable for:
