Propylene Glycol

Propylene Glycol is a clear, colorless liquid with the consistency of syrup. It is practically odorless and tasteless. It is hygroscopic attracts water, has low toxicity and outstanding stability, as well as high flash and boiling points, low vapor pressure and broad solvency. These properties make PG ideal for a wide array of applications, such as:

• Propylene Glycol for Antifreezes, Coolants and Aircraft Deicing Fluids
• Propylene Glycol for Heat Transfer Fluids
• Propylene Glycol as Solvents
• Propylene Glycol used in Food
• Propylene Glycol used in Flavors and Fragrances
• Propylene Glycol used in Cosmetics and Personal Care Products
• Propylene Glycol for Pharmaceuticals
• Propylene Glycol used in Chemical Intermediates
• Propylene Glycol for Hydraulic Fluids
• Propylene Glycol for Plasticizers
• Propylene Glycol for Thermoset Plastic Formulations

 

Propylene glycol is the preferred glycol for manufacturing high-performance unsaturated polyester resins (UPR) for many thermoset composite applications. Propylene Glycol Industrial Grade (PGI)is an excellent choice for these applications.For applications that require more flexible or hydrolytically stable resins, dipropylene glycol is used.

 

Common UPR application areas include:

• Reinforced plastic laminates for marine construction, bathware and shower stalls
• Electrical components
• Pipes
• Tanks
• Ducts
• Sheet molding compounds (SMC) for the automobile and transportation industries.

Non-reinforced thermostat applications include:

• Gel coats
• Buttons
• Synthetic marble castings

Propylene Glycol USP, referring to the United States and European Pharmacopeia, is a high-purity grade of monopropylene glycol for use in pharmaceutical, food, cosmetic, personal care, flavor and fragrance, plus a variety of other applications. The clear, colorless, practically odorless, slightly viscous, water-soluble and hygroscopic liquid with low vapor pressure is produced and handled in compliance with current Good manufacturing unit.
