Propylene Glycol, Industrial - PGI

Propylene Glycol, Industrial (PGI) Grade, is a high-purity material produced by the high temperature and pressure hydrolysis of propylene oxide (PO) with excess water. PGI is a distilled product with a purity specification of 99.5%. PGI is a colorless, water soluble, hygroscopic liquid with a characteristic glycol odor, medium viscosity, low vapor pressure and low toxicity. Propylene Glycol, Industrial Grade, is widely employed in numerous industries, having a wide range of practical applications.

applications:

Propylene Glycol, Industrial Grade, is used in the production of a wide variety of products, including such diverse commodities as polyester resins, engine coolants, latex paints, heat transfer fluids and deicing compounds. It also meets requirements for application in liquid cleaners, lubricants, plasticizers and cement grinding additives. It is employed as a solvent, heat transfer medium, or as a chemical intermediate, taking advantage of its reactive hydroxyl groups.

Propylene Glycol, Industrial Grade, is the preferred glycol for manufacturing high performance unsaturated polyester resins, themselves used in a variety of applications such as reinforced plastic laminates for marine construction, gel coats, sheet molding compounds(SMC), and synthetic marble castings. Aqueous solutions of Propylene Glycol, Industrial Grade, display excellent antifreeze properties, and are, therefore, valuable as low temperature heat transfer and aircraft deicing fluids. PGI is an important co-solvent for architectural water-based paints, and is also used as an intermediate in the production of alkyd resins for paints and varnishes. Its solvency lends its use for liquid cleaners, including the stabilization of enzymatic liquid laundry detergents.
