Product Description

Product Description

Propylene Glycol, Industrial (PGI) Grade, (CAS #57-55-6, 1,2-Propanediol) is a high purity material produced by the high temperature and high pressure hydrolysis of propylene oxide (PO) with excess water.

PGI is a distilled product with a purity specification of minimum 99.5% .

PGI is a colorless, water soluble, hygroscopic liquid with a characteristic glycol odor, medium viscosity,

low vapor pressure and low toxicity.

Main Application

• Flotation agent

• Extraction solvent
• The freezing point of water is depressed when mixed with propylene glycol. It is used as   aircraft deicing and anti-icing fluid.
•It is the raw material of unsaturated polyester resin, epoxy resin, polyurethane resin, and also the raw   material of plasticiser, surfactant, emulsifier and emulsion breaker.
•In the food industry, it is used as solvent of flavour, food colouring, tobacco wetting agent, mould inhibitor   and fruit ripening preservative, drug excipient and so on.
•It can also be used as antifreeze, heat carrier and food machinery lubricant.
