Applications of Propylene Glycols

Like polyether polyols, propylene glycols are also a product of propylene oxide.

1. Dust suppression

• Dust formation and the associated housekeeping issues, plus the danger of dust explosions, make dust suppression important in mining and cement grinding applications

2. Dyes and inks

• Propylene glycols are excellent solvents and compatibilisers for the many dyes, resins and inks used in modern high-speed printing presses

3. Lubricants


4. Natural Gas Dehydration

• When natural gas is recovered, its water content may need to be lowered to prevent water from condensing in pipelines and freezing or from forming hydrocarbon hydrates. Hydrates can foul instruments and reduce line capacity

5. Plasticizers

• A plasticizer is a molecule that is added to a polymer to modify its properties, making it easier to process and/or meet application requirements such as improved toughness or flexibility. Plasticizers function by internal solvation of the polymer chains

6. Surfactants

• “Surfactant” is a contraction of the words surface-active and agent. Surfactants function by changing the surface tension at the interface of mixtures, allowing non-miscible materials to either be dispersed into water or separated from water
