use

1. Propylene glycol is an important raw material for unsaturated polyesters, epoxy resins, polyurethane resins, plasticizers, and surfactants. 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.

2. Used in organic synthesis, used as solvent, dehydrating agent, plasticizer, antifreeze, gas chromatography stationary liquid.

3. Commonly used organic synthetic materials, used to make unsaturated polyester resins. It can also be used as an emulsifier, preservative, and antifreeze. It is also used in the manufacture of alkyd resins, polypropylene glycols, plasticizers, surfactants and lubricants.
