Poly(propylene glycol) CAS 25322-69-4
Poly(propylene glycol) is a polymer with a colorless to light yellow liquid appearance. It is soluble in water (low molecular weight) and organic solvents such as aliphatic ketones and alcohols, but insoluble in ether and most aliphatic hydrocarbons. It is obtained by condensation of propylene oxide and propylene glycol under high pressure or in the presence of an acidic catalyst.

1. PPG series are soluble in organic solvents such as toluene, ethanol, trichloroethylene, etc. PPG200, 400, and 600 are soluble in water and have lubricating, soliloquizing, defaming, and antistatic properties. PPG-200 can be used as a dispersant for pigments.
2. In cosmetics, PPG400 is used as an emollient, softener, and lubricant.
3. Poly(propylene glycol) is used as an anti-foaming agent in coatings and hydraulic oils, an antifoaming agent in synthetic rubber and latex processing, a refrigerant and coolant for heat transfer fluids, and a viscosity improver.
4. Poly(propylene glycol) is used as an intermediate for esterification, etherification, and polycondensation reactions.
5. Poly(propylene glycol) is used as a release agent, a solubilizing agent, an additive for synthetic oils, an additive for water-soluble cutting fluids, roller oils, hydraulic oils, high-temperature lubricants, and internal and external lubricants for rubber.
6. PPG-2000~8000 has excellent lubrication, anti-foaming, heat and frost resistance and other properties;
7. PPG-3000~8000 is mainly used as a component of combined polyether to produce polyurethane foam plastics;
8. PPG-3000~8000 can be used directly or after esterification to produce plasticizers and lubricants;
