Product Name:Dipropylene glycol dibenzoate
English Name:Dipropylene glycol dibenzoate
CAS No.:27138-31-4
Aliases:Dibenzoic acid, dipropylene glycol ester, Dipropylene glycol bis(benzoate)
Molecular Formula:C20H22O5
Physical Properties:Colorless to light yellow transparent oily liquid with a slight aromatic odor. Density (20°C) approximately 1.12 g/cm³, high boiling point (approximately 232°C/5 mmHg), flash point approximately 215°C. Very low solidification point, tending to form a glassy or supercooled liquid at -30°C. Insoluble in water, soluble in most organic solvents such as alcohols, ketones, and esters.
Uses:Mainly used as an environmentally friendly plasticizer for polyurethane and PVC, replacing DOP and DBP. Suitable for PVC floor covering materials, thermosetting plastics, rubber products, coatings, adhesives, and fillers. It offers advantages such as low dosage, low plasticizing temperature, good processing performance, dimensional stability of finished products, and low cost.
Technical Specifications:
Appearance: colorless to light yellow transparent liquid
Purity: ≥98%
Acid value: ≤0.5 mg KOH/g
Water content: ≤0.2%
Flash point: ≥215°C
