Description

Dicapryl Phthalate is a high-purity diester plasticizer derived from phthalic anhydride and capryl alcohol. This compound is valued for its excellent solvating power, low volatility, and compatibility with a wide range of polymers, making it a versatile and effective additive. It is primarily sought after by manufacturers in the plastics, coatings, and specialty chemical industries for formulating flexible PVC, adhesives, and synthetic lubricants where consistent performance and product stability are critical.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) compounds in wire & cable insulation, films, and sheets.
• Coalescing agent and plasticizer in specialty polymer dispersions and latex paints for improved film formation.
• Functional fluid and base component in the formulation of high-performance synthetic lubricants and greases.
• Solvent and carrier in the production of pigments, dyes, and specialty inks.
• Additive in adhesive and sealant formulations to enhance flexibility and elongation properties.
• Intermediate in organic synthesis for the production of more complex ester derivatives.
• Plasticizer for nitrocellulose and other cellulose-based resins in coatings and films.
