Diisodecyl Phthalate (DIDP) is a commonly used plasticizer in the polymer industry. DIDP is a mixture of compounds obtained by esterifying phthalic acid with isomeric decyl alcohols. It is used to increase the flexibility of plastics and plastic coatings.

Properties:

• Chemical Formula: C28H46O4

• Molecular Weight: 446.672 g/mol

• Density: 0.96-0.97 g/cm³ (at 20°C)

• Melting Point: -50°C

• Boiling Point: 250-257°C (at 0.5 kPa)

Applications:

• Coatings: Furniture, kitchenware, pharmaceutical tablets, food packaging

• Automotive: Interior upholstery, cables, and wires

• PVC Products: Flexible PVC products, sealants, mastic applications

DIDP is preferred in applications requiring resistance to high temperatures and low fogging. It is also known for its low volatility and good insulation properties.

Diisodecyl Phthalate (DIDP) is also known by several other names:

• Bis(8-methylnonyl) benzene-1,2-dicarboxylate

• Bis(8-methylnonyl) phthalate

• Bis(isodecyl) phthalate

• DIDP

• 26761-40-0 (CAS number)

These names are used interchangeably in various industries and applications

In everyday language, Diisodecyl Phthalate (DIDP) is often referred to as a "plastic softener" or "plasticizer." These terms are used to describe chemicals that make plastics more flexible and durable. DIDP is commonly used in products like flexible PVC, car interiors, and various coatings to enhance their flexibility and longevity.
