NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of specialty chemicals, and among our most versatile products is Propylene Glycol (PG), known by its CAS number 57-55-6. While its uses in food and cosmetics are widely recognized, PG's industrial applications are equally extensive and critical. Its unique chemical properties make it an indispensable component in sectors ranging from automotive and aerospace to manufacturing and paints & coatings.

One of the most significant industrial uses of Propylene Glycol is in antifreeze and de-icing formulations. Its ability to significantly lower the freezing point of water makes it an effective component in automotive coolants, aircraft de-icing fluids, and industrial heat transfer systems. Unlike its counterpart, ethylene glycol, PG offers a lower toxicity profile, making it a safer choice for applications where environmental or incidental human contact is a concern. The propylene glycol antifreeze function is crucial for protecting machinery and ensuring operational safety in cold climates.

As a solvent, PG finds widespread use in industrial cleaning agents, paints, varnishes, and inks. Its ability to dissolve a variety of organic and inorganic substances makes it an effective coalescing agent in water-based paints, promoting film formation and improving coating performance. In industrial cleaning, its solvency helps to break down greases and oils, making it a component in effective degreasers. The broad propylene glycol solvent properties are leveraged across numerous manufacturing processes.

Propylene Glycol also serves as a plasticizer, increasing the flexibility and durability of plastics and resins. It is used as a chemical intermediate in the production of unsaturated polyester resins, which are vital for manufacturing fiberglass-reinforced plastics, coatings, and adhesives. Its role in these foundational materials highlights the breadth of its propylene glycol industrial applications.

Furthermore, PG is utilized in the textile industry as a dye carrier and lubricant, and in the production of hydraulic fluids and brake fluids. Its hygroscopic nature makes it useful in applications requiring moisture control. The consistent availability of high-purity, industrial-grade Propylene Glycol from NINGBO INNO PHARMCHEM CO.,LTD. ensures that industries can rely on its performance characteristics for a wide range of critical functions.

In essence, Propylene Glycol is a fundamental chemical building block with an impressive array of industrial uses. Its effectiveness as an antifreeze, solvent, plasticizer, and chemical intermediate underscores its importance in modern manufacturing and technology. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying this essential chemical to support the diverse needs of our industrial clients.
