CAS 27138-31-4 Plasticizer Oxydipropyl Dibenzoate DPGDB Dipropylene Glycol Dibenzoate

 

Product Description

Dipropylene glycol dibenzoate (DPGDB) is a chemical compound that belongs to the family of glycol esters. It is formed by the esterification of dipropylene glycol with benzoic acid. DPGDB is a clear, colorless liquid with a mild, pleasant odor. It has a low volatility and is soluble in common organic solvents but insoluble in water.

 

Technical data:

• Chemical formula: C20H22O5
• Molecular weight: 342.39 g/mol
• Boiling point: Approximately 325°C (617°F)
• Flash point: Approximately 210°C (410°F)
• Density: 1.11 g/cm³ at 25°C (77°F)
• Viscosity: 70-100 cP at 25°C (77°F)
• Refractive index: 1.504 at 25°C (77°F)

Features of Dipropylene glycol dibenzoate include:

1. Plasticizer: DPGDB is commonly used as a plasticizer due to its ability to improve the flexibility and durability of various materials. It can be added to polymers, resins, and elastomers to enhance their processing characteristics and increase their flexibility and softness.

2. Low volatility: DPGDB has a low evaporation rate, making it suitable for applications where long-lasting performance is required. It helps to reduce the migration of plasticizers from the material over time.

3. Solvency: DPGDB exhibits good solvency for a wide range of organic compounds. It can dissolve various resins, pigments, and additives, making it useful in coatings, paints, and inks.

Applications of Dipropylene glycol dibenzoate:

1. Coatings and paints: DPGDB is commonly used as a plasticizer for coatings and paints. It improves film flexibility, adhesion, and durability. It also helps to reduce the viscosity of coating formulations, thus facilitating application.

2. Inks: DPGDB is utilized in printing inks to enhance their performance. It aids in pigment dispersion, improves ink flow, and prevents ink drying on the printing equipment.

3. Adhesives and sealants: DPGDB can be incorporated into adhesives and sealants to improve their flexibility and bond strength. It also helps to enhance the workability and processability of these products.

4. Plastics and polymers: DPGDB acts as a plasticizer in thermoplastic polymers, such as PVC (polyvinyl chloride), improving their flexibility, impact resistance, and processability.

5. Industrial and household products: DPGDB finds applications in various industrial and household products, including lubricants, cleaners, personal care products, and automotive fluids.
