Industrial Products
Propylene Glycol is a key ingredient in the production of unsaturated polyester resins, which are widely used in the manufacture of fiber-reinforced plastics (FRP), such as boat body, bathtubs, and various types of pipes. It can also be used as a de-iced fluid for aircraft wings and as an antifreeze in solar heaters and automotive cooling systems.
