• Basic Information
  • CAS No.：25322 - 69 - 4
  • English Name：Poly(propylene glycol)
  • Alias：PPG; Polypropylene alcohol 400; Propylene glycol polyether
  • Molecular Formula：(C3H6O)n
  • Molecular Weight：The molecular weight of general commercial products is between 400 and 2050.
• Physical and Chemical Properties
  • Appearance：Colorless to light yellow viscous liquid.
  • Odor：Odorless.
  • Solubility：Lower molecular weight polymers are soluble in water, while higher molecular weight polymers are only slightly soluble in water. They are soluble in oils, many hydrocarbons, and organic solvents such as aliphatic alcohols, ketones, and esters, but insoluble in ether and most aliphatic hydrocarbons.
  • Density：About 1.0±0.1 g/cm3.
  • Melting Point： - 40 °C.
  • Boiling Point：184.8±8.0 °C at 760 mmHg.
  • Flash Point：107.2±0.0 °C.
• Performance Characteristics
  • Lubricity：It has good lubricating performance, which can reduce the friction between products and the contact surfaces of containers and pipelines.
  • Solubilization：It can improve the solubility of drugs, cosmetics and other products, making them easier to be absorbed and utilized.
  • Defoaming Property：It has defoaming effect in coatings, hydraulic oils, synthetic rubber and latex processing.
  • Antistatic Property：It has a certain antistatic property.
• Production Process
  • It is obtained by the condensation of propylene oxide and propylene glycol in the presence of high pressure or an acidic catalyst.
• Main Uses
  • Industrial Field：It is used as a release agent, solubilizer, additive for synthetic oils, additive for water - soluble cutting fluids, roller oils, hydraulic oils, high - temperature lubricants, internal and external lubricants for rubber. It can also be used as an antifoaming 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. It can also be used as an intermediate for esterification, etherification and polycondensation reactions.
  • Cosmetic Field：PPG400 - 2000 can be used as a skin - conditioning agent, softener and lubricant.
  • Medical Field：It is used as a solubilizer, stabilizer and lubricant for drugs, to improve the solubility, stability and usability of drugs.
  • Food Field：As a food additive, it is used in the production of candies, beverages, seasonings, etc., to improve the taste and stability of food.
• Packaging and Storage
  • Packaging：It is usually packaged in 200L plastic barrels or iron barrels, and there are also 50kg plastic barrel packaging.
  • Storage：It should be stored in a cool and dry place with the container sealed.
