Industrial Grade Propylene Glycol (PG), known by its CAS number 57-55-6, is a critical chemical used across a vast spectrum of industrial applications. From serving as a vital component in antifreeze and coolant systems to acting as a solvent and chemical intermediate, its utility is undeniable. For businesses requiring a reliable and cost-effective supply, understanding the sourcing landscape, particularly from established Chinese manufacturers, is key. This article delves into the properties, industrial applications, and strategic advantages of sourcing industrial PG.

Propylene Glycol is a synthetic diol characterized by its colorless, viscous liquid form. It is virtually odorless, possesses a slightly sweet taste, and is highly hygroscopic, meaning it absorbs moisture from the air. Crucially for industrial applications, it is miscible with water and many organic solvents, enhancing its utility as a solvent and carrier fluid.

Key Industrial Applications of Propylene Glycol

The industrial sector leverages Propylene Glycol for its unique properties in several key areas:

  • Antifreeze and Coolants: PG is widely used as a less toxic alternative to ethylene glycol in antifreeze formulations for automotive, HVAC, and industrial cooling systems. Its low freezing point and non-toxicity make it a safer choice where incidental contact might occur.
  • De-icing Fluids: In aviation and ground de-icing applications, PG-based fluids are effective in removing ice and preventing its formation, ensuring operational safety in cold environments.
  • Solvents and Chemical Intermediates: PG serves as a powerful solvent for various industrial compounds, including paints, coatings, and inks. It is also a fundamental raw material in the synthesis of polyester resins and polyurethanes, contributing to the manufacturing of plastics and foams.
  • Hydraulic Fluids and Lubricants: Its lubricating properties and thermal stability make it suitable for use in certain hydraulic fluid formulations and as a component in industrial lubricants.
