Propylene glycol is an important raw material for unsaturated polyester, epoxy Resin, and polyurethane resin. The amount in this area accounts for about 45% of the total consumption of propylene glycol. This unsaturated polyester is used in large quantities for surface coatings and reinforced plastics.
