Propylene Glycol (CAS 57-55-6) is far more than just a cosmetic or pharmaceutical ingredient; it's a workhorse in numerous industrial applications. Its unique properties as a solvent, antifreeze agent, and chemical intermediate make it indispensable for sectors ranging from automotive to manufacturing. As a leading manufacturer and supplier in China, we offer industrial-grade Propylene Glycol that meets the robust demands of these critical industries.

This versatile diol, a colorless and viscous liquid, is characterized by its low toxicity and excellent miscibility. These attributes, combined with its ability to depress freezing points and act as a heat transfer medium, make it an ideal choice for many industrial processes. When you buy Propylene Glycol for industrial use, you're investing in reliability and performance.

Key Industrial Applications:

  • Antifreeze and Coolants: Propylene Glycol is a preferred alternative to ethylene glycol in many antifreeze formulations due to its significantly lower toxicity. It effectively lowers the freezing point of water, protecting engines and cooling systems from frost damage. It's also widely used in aircraft de-icing fluids and industrial heat transfer systems, providing reliable freeze protection and efficient thermal management.
  • Unsaturated Polyester Resins (UPR): A significant portion of industrial Propylene Glycol is consumed as a feedstock for producing UPR. These resins are vital components in the manufacturing of fiberglass-reinforced plastics, used in everything from boat hulls and automotive parts to building materials and pipes. Our role as a manufacturer ensures a consistent supply of the quality required for resin synthesis.
  • Hydraulic and Brake Fluids: Its stability and lubrication properties make it a component in hydraulic fluids and brake fluids, contributing to system performance and longevity.
  • Paints and Coatings: Propylene Glycol can act as a solvent and coalescing agent in water-based paints and coatings, improving film formation, dry time, and overall finish.
  • Cleaning Agents: It is used in industrial cleaning formulations due to its solvency and relatively low environmental impact.
