Dipropylene Glycol (DPG), Regular Grade is colorless, nearly odorless, and has medium viscosity with hygroscopic and water-soluble properties. Its low toxicity and vapor pressure add to its characteristics. It's a mixture of structural isomers (known as oxybispropanol with CAS number 25265-71-8.)
Applications :
Dipropylene Glycol, Regular Grade, is used as a solvent, coupling agent and chemical intermediate. Typical applications include:

1. Esterification with benzoic acid to make dipropylene glycol dibenzoate for plasticizers.

2. A reactant in unsaturated polyester resins to add flexibility and hydrolytic stability to the finished resin.

3. Esterification with acrylic acid to make dipropylene glycol diacrylate for radiation cured resin formulations.

4. In dicyclopentadiene-based unsaturated polyester resin systems to add flexibility.

5. An initiator for urethane polyol synthesis using epoxides, and for the polyol in rigid polyurethane foams.
