Propylene Glycol Industrial Grade (PGI) is a colorless, odorless and slightly viscous liquid.


  • Unsaturated polyester resins.
  • Coolants and Antifreeze.
  • Hydraulic and Brake Fluid.
  • Aircraft Deicing Fluid.
  • Heat Transfer Fluids.
  • Paint and Coatings.

Benefits to the customer

Its properties make it suitable for the following uses:

  • As aircraft de-icer, enabling safe air transport and ensuring that surfaces are smooth enough for the aircraft to stay in the air.
  • In paints and coatings, providing sustainable weather and wear protection.
  • In liquid detergents, improving hygienic conditions.
  • As a basic building block in the production of other formable plastics such as unsaturated polyester resins (UPR) used e.g. in construction, ship hulls, automotive and electrical components, furniture, heavy-impact surfaces (floors, kitchen, bathroom) or wind turbine blades.
