Propylene Glycol (PG), scientifically identified by CAS number 57-55-6, is a cornerstone chemical with a wide array of applications in the industrial sector. At NINGBO INNO PHARMCHEM CO.,LTD., we supply high-quality industrial-grade PG, appreciating its multifaceted utility. This overview aims to provide a comprehensive understanding of its properties and diverse applications that make it indispensable to modern industry.

The fundamental characteristics of industrial PG—its colorless, odorless, slightly viscous, and hygroscopic nature—lay the foundation for its widespread use. Its miscibility with water, acetone, and chloroform makes it an excellent solvent, capable of dissolving a broad spectrum of substances. This makes it a valuable component in formulations for paints, coatings, inks, and various industrial cleaning agents, where it acts as a solvent, viscosity modifier, and humectant, ensuring product stability and desirable application properties. When sourcing industrial propylene glycol, the consistency of these properties is key to achieving reliable results in manufacturing.

A significant application area for PG is its use as a heat transfer fluid. In industrial processes requiring precise temperature control, such as in chemical manufacturing, pharmaceutical production, and HVAC systems, PG-based fluids offer excellent thermal stability and efficient heat exchange capabilities. They perform effectively across a broad temperature range and, importantly, have a significantly lower freezing point than water, preventing system damage in cold environments. This makes PG an essential ingredient for ensuring operational continuity and safety in many industrial cooling and heating applications.

Furthermore, PG's role in creating antifreeze and coolant solutions is well-established. Its ability to depress the freezing point of water is critical for protecting engines, pipes, and other equipment from freeze damage. When seeking reliable freeze protection, many industries turn to PG due to its efficacy and favorable safety profile. This makes it a crucial chemical for sectors operating in regions with extreme weather conditions.

The versatility of Propylene Glycol extends to its use as a chemical intermediate in the production of unsaturated polyester resins (UPR). UPRs are widely used in fiberglass reinforced plastics, coatings, and adhesives, benefiting from the strength and resin resistance that PG imparts. This application highlights PG's importance in the manufacturing of durable goods and construction materials.
