Diisodecyl Phthalate (26761-40-0)

Diisodecyl Phthalate (DIDP) is a phthalate ester plasticizer with the chemical formula C28H46O4 and molecular weight 446.67 g/mol. It appears as a clear, colorless to pale yellow oily liquid. It is insoluble in water but soluble in organic solvents and oils. It is stable under normal conditions, has low volatility, and good compatibility with PVC and other polymers.
In terms of uses and applications, Diisodecyl Phthalate is widely used as a plasticizer for PVC and other polymers to improve flexibility, softness, and durability. It is commonly used in wires and cables, flooring, roofing membranes, films, hoses, and coated fabrics. In the automotive industry, it is used in interior trim and synthetic leather applications. It is also used in sealants, adhesives, and industrial plastics. Additionally, it finds application in specialty polymer formulations where high-temperature stability and low volatility plasticization are required.
